for girls, prep is something that both of you and your partner should do, like foreplay, finger, and touching boobies. It will bleed if you have hymen but not all women have hymen so it will just hurt, sting like tearing tissues if your vagaygay is not lubricated or aroused enough. for men, the process will be so long since the anus will not lubr......
From experience, you will need a lot and I repeat A LOT of foreplay to get in the mood and get wet down there, even so it would probably hurt. If it hurts to the point you feel uncomfortable, you should stop, you can continue later with more lube. But it’s never fwop schlop slurp that’s for sure.
It shouldn’t hurt. If it hurts, you’re doing it wrong. It’s def uncomfy tho at first (I can’t speak for dudes)
