he can’t cum

i posted this on another topic board on here but i’m trying to get some more perspectives.

i’m so utterly embarrassed by this but i need help and maybe some answers. i’ve been hu with this guy at college the last few weeks and every time we’ve hooked up it’s been after a party or something so he’s usually had alcohol. he blamed the first time when i gave him head and he didn’t cum bc he had whiskey dick which was fine bc he couldn’t get himself off either, so it made me feel better. but now we’ve had sex twice and he hasn’t came then either, and it makes me feel like shit about myself. mind you, i let him take my virginity so i’m relatively tight, not that it matters. but he keeps asking for me to give him head after sex bc he didn’t cum and i don’t want to try to do that again and he doesn’t cum because then i’ll feel worse about myself. i don’t know what to do or what i’m doing wrong, i’ve never had this issue before. oh and to make matters worse, he pulled up porn on his phone after we had sex and wanted to go jerk off in the bathroom. i get not wanting blue balls but that’s weird right? like i should be slightly offended by him pulling up porn not even 5 minutes later? i don’t know, someone help a girl out please
