Depression meds & orgasm

Laykin

So I’ve recently been exploring my sexual side now that I’ve had a boyfriend and I’m 18. I used to be on Zoloft and would get super horny, but I feel like I would stop myself from cumming. I switched over to celexa and after like the 4th week it’s like I can totally live without sex and I get sore before I can cum. Is that normal and how do I stop it? I want to be able to have an orgasm, but it just seems that I can’t or that I get too sore And the minute me and my boyfriend stop I’m good. And he’s good so I don’t understand. Are we just not going long enough? How long are we supposed to go? And could this be my meds? And any other tips on different meds for anxiety?
