I believe the creator was not willing to go this far. Yes, the clothing is revealing no matter which sex for character creation; but it's more of an artistic choice for character creation.
If you want to go that far, you are better off modding the game. Beyond that; I'd rather see this game get done and reach completion first. Then worry about other details like this after or not at all.
They aren't as noticeable irl and even then, Kiseff isn't planning to add any H-Content or anything sexual because they don't want too. This is still an Artistic choice and it's in the FAQ; 6th bullet making note on Jiggle Physic's and asking about sexualized content.

There is a possible modding scene; you might go to modify to add this feature later. Trying to push this when the developer is just trying to get it finished isn't going to make them add it or consider it if they are trying to just get this done.
How are boobs not sexual but bulges are? When i say bulges i dont mean a literal outline of a cock just a bulge.
" They arent noticeable irl" This might be a difference in culture because i dont know how American beaches are but in my country its extremely normal to see guys in speedos and so are bulges, but you wont be seeing anyone that has a underwear that explicitly outlines their dick.
Again if the dev doesnt want to add them its fine but if the reason for that is that they are too sexual i think thats a stupid reason cuz the difference between them and large breasts is literally none.
Because we see boobs daily, no matter where we look. Your mother? Boobs, The girl up the street, girl at the Mc Donalds Counter, Woman in the office, it's impossible not to notice and more impossible to remove boobs to tell a gender between male and female.
Folks in my country don't wear Speedos with the exception of folks who do visit to wear them as their whole custom.
Lastly, just mod them in man if you are going on a Tyrade.
My guess is it's just common culture right now. If you were to go to a beach wearing a speedo here in the US you'd get a lot of flack for it, especially considering that bulge is genitals while boobs and butt are not. Japan is probably the one place where someone would add a feature like this without a second thought (and even then, they just might not include it because women are more popular, even with women to a degree, because Japan isn't Ancient Rome).
I would wait for a mod like Quto said.
