My boyfriend, who is 19, thinks that sex takes up too much time.

My boyfriend and I just moved in together, and we were really excited about finally having some privacy after sharing a space with two roommates and dealing with thin walls. We thought we'd be able to enjoy our intimacy without worrying about being overheard. Recently, while we were getting cozy, I started to sense he was trying to initiate something, but then he halted and went back to playing on his PC. Later, I mentioned to him that I felt he was building up to something, and I was a bit let down to find out he was just joking around. He then shared that sex takes up a lot of his time, which discourages him. This really hurt my feelings, especially since he easily carves out time for his friends and gaming without hesitation. Why is being intimate perceived as such a hassle? I wanted to know if there was something I could do to make it feel more worthwhile, so I expressed how his comment affected me. He opened up about his anxiety regarding lasting too long and worrying that it might be disappointing for me. Yet, I can't help but feel that it's more disappointing that he's hesitant to even try being intimate with me. I later asked him what the biggest obstacle was, and he said it was definitely the time commitment involved. I'm unsure how to make intimacy seem as appealing as other activities or help him understand how much his comment affected me.
