I (20F) and my boyfriend (21M) had sex for the first time, both virgins prior. We've been together for 3 months now. He didn't seem to enjoy it while the act, and after he finished, he said masturbating by himself is better than sex. I consider myself pretty attractive, I'm fit, small waist and all and I don't think it has something to do with my body but I do have self harm scars all over so it might be bugging him? He knew that I have them though… I can't help but think I'm undesirable and unattractive now. We had it 4 times in a day and after it was done, he felt disgusted and now anytime we talk about something sexual, he just feels repulsed by the topic and says he might be asexual, but he couldn't wait for the day that we had sex. He says he doesn't even want to touch my boobs for a while which I completely understand, I'm not gonna make him touch me, I just don't understand the reason why he was so excited to do it and see me naked before the act but after it was done he doesn't even want to think of it. He says he wants to wait for a while to see if he gets better, I'm okay with it, only kissing from now on. I know that sex is not everything in a relationship and emotional connection is better so I don't mind him not wanting to have sex but the thing is, he feels repulsed by the act. He doesn't enjoy it and it makes me feel bad, I want to make him feel good but it didn't work. As I said, only kissing from now on until he feels okay? but it's just so weird that he thinks masturbating is better than sex when he couldn't wait for it, and is now disgusted.
TL;DR: boyfriend doesnt enjoy sex and thinks masturbating is better, needs space and time to see if he gets better because he thinks he's asexual
