I'm almost embarrassed to ask about this.. Forgive me if I'm too frank!

I'm 13 weeks and we've been having sex all along, even during the horrid MS. Well, lately.. Sex feels different. At first I thought it was a friction thing, as now, I tend to be a little... Slicker. But I'm realizing its more about just not getting the same pleasure out of it, even though I'm turned on. It just doesn't feel like it normally does. Like.. My "happy button" is only at 50% sensitivity.

I can't tell if it's a ME thing, or if he just isn't as "up to it".. Whatever the case, it has me insecure and nervous and honestly, depressed! Anyone else having issues?
