I had a discussion with a friend recently and during that discussion, one comment was "Fitted sheets are really both the best and the worst", of course referencing them as awesome when put on a mattress and the worst when you're trying to fold them.
What else do we have that would qualify for being awesome, but also the worst in a different context?
So...sex on an SSRI.
Pro: I can effortlessly last over an hour. Basically edging without trying.
Con: It's simply impossible to finish sometimes and I just have to say it was good enough and stop. Or the mix of chemicals in my brain just don't let me start for whatever reason. The times I can finish, I have to take over and go extra intense on myself to peak the mountain. If my partner tries, they can't get me there.
