I was having some vaginal irritation issues at the start of our relationship, so we didn't start having PIV sex on a regular basis until about mid-January, just about two months ago.
He's also on Celexa, or a generic. I suspect the particular type of pill he was taking changed (even though he insists otherwise. He switched doctors and got a new prescription. Other side effects have changed, too, and when it comes to things like this, [much as I love him!] he is not the most observant guy ever).
So, my question is, could the loss of sensitivity be attributed to a change in pill? Or any of the other reasons listed? Any other ideas?
