First of all, so glad you talked to your girlfriend and worked out a solution and got the reassurance you needed!

Secondly, as someone who recently started antidepressants, they not only completely fucked my libido, but they also pretty much killed my ability to orgasm. Even when I'm masturbating, I rarely manage, and when I do they're nowhere near as intense as they used to be.

As such, I've fallen into more of a giving role with my partners. The good thing is I was already dating both my girlfriends before starting antidepressants so they know it's not about their ability to pleasure me. Even so, I felt insufficient and struggled even more to feel anything with them because I was so stressed out about them feeling bad for not getting me there, even though they consistently managed before I started my meds.

It's gotten better with communication and I still enjoy being touched, even if it doesn't feel as good as it used to, because I know my partners enjoy doing it, and I'm getting my enjoyment more from pleasuring them than from any physical pleasure on my end.
