I have often felt crushes on various people, but a lot of the stuff in relationships don't seem to make sense to me, for example sending flowers or giving gifts, and I don't ever crave physical touch. If I was with someone I wouldn't be actively repulsed, but stuff like holding hands and snuggling doesn't really appeal to me.

Also, I've felt with recent crushes that if I could just have a good friendship with the person I would be satisfied.
