I have been seeing my current boyfriend since November. We don't live in the same city but we met when he was up visiting a mutual friend. We spent a lot of the week he was up talking and getting to know each other with the encouragement of our mutual friend but never spent the night together as he was staying with my friend and we didn't want to take things too quickly. When he left we agreed to give things a go even though it would be exclusively long distance for the first few months because of other commitments.
We spent the next few months texting every day and calling as often as we both could and it all felt really lovely. The next time we met in person was the beginning of March when he came up to stay for a week. This time he asked if it would be ok to stay at mine. I was very happy that he suggested this. On the first night he was here we had sex for the first time. He was very respectful it was overall very positive, but I noticed he never finished which made me worry it wasn't so good for him. I did't mention it to him at the time because I didn't want to make him uncomfortable, but the next day when we had sex again the same happened. I think he could tell I was slightly worried so he told me that he'd never been able to finish from sex and that it didn't stop him from enjoying it.
I really appreciate him telling me that but I've never come across this before in someone and can't tell if that's just something he's saying because he doesn't want to hurt my feelings. I asked one of my friends that he doesn't know what it means if someone can't finish and they confidently told me it's usually because they're not attracted to their partner. Since this conversation I've been overthinking this quite a lot but didn't want to talk to too many people I know about it because I don't want to embarrass him.
So, was just looking for some advice, reassurance or just any thoughts anyone might have on my situation.
