My connections with other people do seem to play a role. If there is friendship or romantic interest, usually accompanied by aesthetic interest, I am more open to sexual things. I don't desire them more often, but I'm more receptive when they are offered, and I enjoy it if the other person knows my happytriggers (words/intellectual foreplay for me.) If there is no connection with the other person, sex won't be happening, since it's not something worth seeking out on it's own for me.

People are hard enough and I'm awkward enough that I won't seek out one night stands. If I don't have a partner I like, solo orgasms are much easier and more satisfying for me. That said, when I have a partner who doesn't expect sex all the time and knows how to press my buttons, it can be pretty fantastic.
