My boyfriend can't cum :(

He just started on antidepressants and he still gets horny as usual, gets boners REALLY easily for a grown man 🙊😂 but he can't cum from sex, oral, or even jerking himself off. My poor baby has constant blue balls :(

I was on the same meds he was on for a while and had the same issue, but never tried to fix it, just switched my meds... but he can't do that right now :(

Any tips/ tricks/ products??
