Kukushka
1. There is nothing wrong with having sex with hair. That's how nature intended it. So it's not like it was "his fault" for not informing you of a danger.
2. It was YOUR responsibility to let him know if he was being too rough or making you itchy. If you have sex with him again, bear this in mind. You don't have to just sit there and let him do whatever he wants. If it's making you uncomfortable, tell him.
3. Yes, it is possible to get pregnant from humping. The hymen is not a magical anti-pregnancy barrier. You NEED to use protection every single time you are sexual with another person.
1) Kukushka's right. You can have hair, or you can be shaved, or have just a little hair, etc. It's your body. If you think your boyfriend might not like it, talk to him and see what he likes, and maybe you two can compromise if he likes something different than what you like.
2) You need to speak up if something is bothering you or if something's making you uncomfortable. If you can't speak up and communicate things like this to him, then maybe you shouldn't be having sex. It's hard to have a good relationship, a sexual one at that, if you can't even communicate to your partner when you don't like something, or when something is bothering you.
3) YES. Anytime sperm gets in your v****a, whether it be pre-c**, ejaculate on his fingers when he pentrates you with them, etc, you CAN get pregnant. If you're dry humping, wear layers of clothes (like not just undergarments), and/or use a condom. Going on birth control in preparation for actual intercourse would be a really good idea too.
