Is it normal to be really grossed out by things you've done with somebody?

You two agreed on being "friends with benefits". Not boyfriend and girlfriend. So it's really none of your business if he was having sex with or dating another girl, he had no obligation to you. He wasn't your boyfriend, you were just booty call and you knew that so why'd you get so mad?

Unless he was deceiving you on purpose. Unless you had a verbal agreement not to see other people. Otherwise, I don't think he did anything wrong. Neither did you though. You probably just should have made it crystal clear what you expected from him. Lol can you tell I've been in his shoes before?

You expected him to be with JUST you, yet you say he is just a friend with benefits? That's kind of contradictory. It sounds like you got attached, wanted him for urself, and got mad when u found out he was doing what any guy would do in that situation, playing the field. And on that measure, sex with anyone should disgust you if u thinking about all the people they've been with before u. And if ur using protection it shouldn't mAtter. You sound young, use it or lose it. One day ur gonna be old and wrinkly and ur gonna look back at this and say, "why the hell did I throw a perfectly good guy away over a miscommunication?"

Story of my life.

Yes! Yes! Yes! Deny it ever happened!

Stupid! Friends with benefits means its only about the sex and outside of that who cares what the other is doing. Sounds more like you were his girlfriend and got pissed because he cheated.

Yup. In fact, feelings aside, I puked after doing things with everyone but my current FWB.

Yes, that is normal. It sounds like you are a little mad at yourself for getting involved with someone who lied to you about the other girl and that is typical. Just learn to forgive yourself and look upon your past relationship as a "learning experience" rather than a "mistake".

omg i had the same experience with a guy a while back. it was one or those moments you kinda just lose it and now i think about it and i want to vomit. totally normal i reckon :)

iam here for youuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu..................................................................................................................................................................................................

completely normal while i've never had a friends with benefits situation i've hooked up with a couple guys friends before and maybe because i think it's too awkward afterwards or whatever i'm not friends with them anymore so i regret losing those friends. i don't hate them but i do wish it ended differently.

The things you did with him, you've described as gross, but it appears that they did not begin to cause the reactions you described until after you found out about his other "friend". So the question is what really grosses you out, the things you did with him or the fact that he was seeing someone else and did not tell you about it?
Remember that by definition the very nature of a "friends with benefits" experience is the lack of exclusivity. Unless you both had an explicit discussion prior to the sexual experience with the friend, and an agreement on the issue was reached, your friend did little wrong. Try to be honest with yourself and determine what exactly is so upsetting and disgusting about this situation, take responsibility for your part in this, accept what was not under your control to change, and reflect upon what sexual acts and relationships are within or without bounds for you.
best of luck

Yes, I think a lot of us have those kinds of experiences. I have some gag-worthy memories myself; actually I'm nauseated cause I'm thinking about one now. I am forever hearing my friends mock each other out about those kinds of things too...

Yes this is very normal. I was in the exact situation, so exact this scares me. And the fact that I liked him and he never wanted a relationship with me, and then him saying that he "loved" the other girl, disgusted me the most. The betrayal feeling disgusted me more than our physical history.

I would say yes its normal! you are human and you have feelings. its good to talk about it and get it out. mabey in counceling you need to be able to put this behind yourself and move on so you can have a normal relationship and sexual functions in the future. good luck.
