Let's see if I can answer this.

1) Is getting pregnant with goblin female, mermaid or spider eggs considers to be a good thing or a bad one? I I mean when I first saw what happened during encounter with spider woman, I thought it is a bad end and loaded earlier save and after losing a fight to a gobling girl she place her goblin egg in Hiro. So far I tened to avoid MC being pregnant, because  I kind worry that he wont survive the birth. So my next question in this regard so if Hiro got pregnant. how does he gave birth, I mean does he need to go to some special clinic? And does  giving birth do anything to him specifically like in negative or positive way?

Well, not all pregnancies are ... problematic, shall we say.  I've managed to have my Hiro give birh once or twice to spider babies and didn't die ... but it's rare.  There are some who have managed it as well and have come up with a formula for it.  I'd suggest you check Google.  Tales of Androgyny Game Spider Babies.

Goblin female eggs you.  You can have a few encounters with werewolves safely.  After two, you'll have a bitch score of two and wind up the werewolf's bitch for life.  Band end.  Same goes if you get egged by the goblin female and have sex with a centaur.  You get a couple of times, then bad end, you've become the mare for the herd.  I don't think you can get pregnant by a goblin male fertilising the gobbo eggs the female lays in you.  Pity that.  As for HOW Hiro gives birth, I'll leave that up to your imagination.  It doesn't kill him though.  No, there are no clinics.  He can even have mermaids!  Fascinating that.  =)

2) Every time Hiro is being taken by anyone I notice that his purity and diginity stats lowers. What happens when it hits zero? Is there any way to gain purity and diginity back?

I've been playing for a while and I have yet to gain back purity OR dignity and I have been down to zero.  Zero only opens you up to some much lewder stuff.  Is lewder a word?  I'll have to go look that up.

3) how exactly combat works. Well I do understand how traditional combat work there, but the alternative way, when you hit "Seduction" ability. what I do need to win? Like getting adversary to zero his stamina or do something else? For example when I in battle with dark magician, when I hit seduction it seemed like it didnt do anything. she just continue to do physical attacks on Hiro

There are various stances, but I'll leave that description for the game.  As for seduction, the randier or hornier your opponent, the better chance their hits don't hit as hard etc....  Now, if you use seduce and get Hiro good and hard, you can grapple, take down, then penetrate and give them a sound one from behind.  Conversely, if they manage to knock Hiro down after Hiro got them good and randy, erm... Look Out!  You literally need to watc your opponent's cock meter to tell how randy they are.  If you get them randy, then present arse, they might decide to top.  Some opponents will eventually lose interest in fighting all together and Hiro wins ... or maybe loses, by taking one for the team.

The best advice I can give is, save before battle, then give things a try.

4) Perhaps a bit an odd question, how armor items work here, like I really dont understand what cage/plug part of armor do in term of gameplay?

Erm ... some plugs, for instance, a tail plug, will excite your opponent.  It gets the werewolf mad with lust after you win, even if you're weak enough to get away unscathed.  See, if your strength is six or better, you're going to play bitch, win or lose.  If Hrio's weak enough not to play bitch after winning, meaning strength is five or less, but he has a tail plug in, Hiro gets to bottom as the bitch.

Armour does what armour does.  It lessens the strength of the hit.  You still take a beating, but not as much of a beating.

Cages keep Hiro from topping.  Plainly and simply, wear a cage over your penis and it doesn't go in.  Therefore, if Hiro wears a cage, he can only bottom.

Last question - does experience only  gains from winning combat battle or there is another ways as well. It just I was playing the almost all eveining but I only got to level 3

Erm... you gain experience when you win a battle.  You gain more experience if you top and sometimes bottom after the win.  As an example, win against the goblin female and you get one experience point.  Now that you've won, give her a ride, or stick it to her and you get another experience point.  Some opponents only give you 1 XP.  Some give 2, others can give you as many as 30 XP.  Take out the Beast Mistress and you can get five or six XP.  You need something like 10 XP to get to level 2 IF you're a Lowlander.  If you're a Highlander, or have elf blood, you need more XP to level up than a lowlander.  That sort of thing.  There are benefits and detractions.

Now, if you ignore levelling up and defeat the Quetzel Goddess at level one, you get a bonus point next time you start playing the game.  For each achievement, of which I believe there are twelve, you gain points.  Points can be used for extra food, extra money, a free key to your cage, armour, clothing, etc....  If you check the ironman box, that means no saving until beating the Quetzel Goddess, then defeating her.  That's an achievement, but it's something like a multiplier.  I've played so often, I routinely get 40 bonus points at the start of the game, since I've won playing the Ironman thingie something like five times.

Achievements are NOT all good ends!  If you get a bad end for laughing at the Brothel Madam, then playing chair, you get seat of power.  Lose to the beast mistress three or four times and you get a different achievement point.  Become a bitch to the werewolves and you get a different one etc....  Do NOT be afraid of bad ends!  Sometimes, bad ends are actually good for you!  Somewhere here ... or maybe it's at https://f95zone.to/  someone posted a full list of possible achievements and how to get them.  Trust me, there is a crap ton of stuff you'll miss out on if you avoid bad endings.  Even being a Mare is one of them.  Become the gadgeteer's play thing and get one.  Loads of stuff.

Hope some of this helps.
