Being with my girlfriend can get me in the mood for sex, but otherwise I'm indifferent. My sex drive's a lot lower than it used to be and that's been a good thing for me because before it just felt like a bodily obligation and gross.
When I do have sex, it's mostly just for the emotional experience with another person. The physical pleasure is pleasant too I guess, but alone it's kinda boring. I just like seeing them happy :)
Took me a while to accept the label, given I do technically enjoy sex. Eventually I realized demi matches my experience decently well.
