<human>: First off, apologies if this isn't the correct subreddit for this, I wasn't sure if it should go here or r/sex.

Anyway, I've been seeing a new girl that I am extremely interested in and attracted to for about a month now. I know I'm really into her and as best as I can tell she feels the same about me, and things have been going well between us. Last night I stayed over at her place for the first time, one thing lead to another and we tried having sex. And of course, for the first time in my life (outside of whiskey dick at least), I couldn't get it up. This has legitimately never been a problem for me, and in fact I find it even more frustrating because in my last relationship I had a much higher libido than my girlfriend and it created a rift between us. Now I'm seeing a new girl with a high libido who is very sex positive and *I'm* the one having problems, and I don't know how to handle it.

I know I'm completely over my ex so there's nothing involving her that could be coming into play with this. I *am* on an anti-depressant that I've been taking for about six or seven months (citalopram) which my doctor informed me could have negative effects on my sex life, it just wasn't a big concern at the time cause I wasn't sexually active. I am going to talk to my doctor and see if there's something else I can be prescribed that won't impact my sex life at all, but in the meantime I'm just worried of how it's going to come off to the girl. She was understanding of the situation but I can tell it bothered her, and rightfully so.

So basically, is there anything I can do to help alleviate this issue until I can get a new prescription and wait for it to start taking effect on me, would something like viagra or cialis help? And on top of that, what can I do to ensure my girl doesn't lose interest in me or form/hold some negative opinion over it?

Can you condense the text into three sentences or less?
<bot>: Seeing new girl I really, really like. First time we try to have sex I can't get it up, then become really self conscious about it and worried how the girl in question is going to take it. Need halp.
