I was on celexa for for a few years for anxiety.it massively reduced my libido. I could almost never come. After a while I had a hard time getting erections. Note I was 32ish when I started it, can’t recall how old you said you were but it might be different for you .. Everyone is different and reacts differently. I do know that the SSRIs are very well known for their libido-reducing effects. My doc supplemented me with some wellbutrin and reducing the celexa (which probably wasn’t wise since I don’t think wellbutrin helps anxiety, just depression). I was on a small dose of wellbutrin and celexa combo, I noticed rock hard erections almost immediately (I think I was taking ginko biloba at the time too - I know it wasn’t the ginko since I still take that and do not notice the same effect at all). I went to go totally to wellbutrin but had a “reaction” to the increased dosage (hives, itching).
I am no totally off the meds after what seems to be a few years.
In the end, I am glad I took them. I needed them at the time - they helped me through a time I may not have gotten through very well otherwise. Now that I am off them I think I have returned to my usual sexual self - no problems with erections or ejaculation.
That being said, there is no reason not to try wellbutrin first. In fact, I have read articles where wellbutrin was touted as a sex enhancer, and I would tend to agree based on my brief usage.
Also, I would HIGHLY recommend frequent cardio exercise. Enough to get your heart rate quite high and for at least 30 minutes (at a minimum). Then take a nice shower and feel the endorphins flow over you. If you go on antidepressants I would treat it as a “stopgap” measurement to allow you to get other coping mechanisms in place so you can eventually go off them. Like I said, exercise, outdoor activity are great starting points. You might also want to check into meditation and relaxation exercises. Keeping busy really does help as well - it is easy to go batty if you dwell on things too much.
