Buddy that is a question for a girl(don't ask to your gf or wife,If you ever want once again) ask her why they like to put that thing in their mouths so much,is it just to give pleasure to their lovers or they actually feels nice while giving a bj
all the relationship s I was in was 15 yrs ago. Since then I've done nothing like that. I date and there's drinks and hanging out. But it never goes beyond that to love making. But yeah, I guess I'll have to just ask one if there comes a time I find a girl I like like that again.
best of luck for that buddy,my best bet is to give pleasure to their lovers,and they try to find pleasure in that,but good luck in finding a new lover to you.
