My bf is sexually frustrated and I don’t know what to do

Hello everyone! So, I have been dating my boyfriend for about half a year and he’s been feeling very frustrated sexually. We’re both in college, so during that time it would be hard because we were on a time constraint to when our roommates got back so it wouldn’t happen often, and the same thing now where we’re at home so we have even less time due to our families being home. Penetration hurts for me so we usually just do foreplay, but every time he’s not able to cum. I’ve been trying new techniques and doing research on ways to better what I’m doing, but so far nothing seems to work. I am his first sexual partner and relationship and he is also on antidepressants, so these are a couple possible factors. But he is just very upset and feels I am not there for him during this, which truly I have been trying. I have never had this problem with past relationships and I’m at a loss of how to handle this and what to do as everything else is great besides this. Any help or support from others who have gone through this would be appreciated, thanks!
