I'm talking about sex. Not casual sex, but other kinds of sex. I have this friend, and I don't know if I love him and I don't know if he loves me, maybe we love each other maybe we're just good friends I'm not sure, but we experiment sometimes and last time we decided that we (as in me) weren't ready for sex. But now I'm wondering, do I have to be in love for it to mean something? I don't want meaningless sex, but how can it be meaningful sex if I'm not in love?

What types of sexual relationships are there? Not physical sex, but is there more to it than love, casual, or friends with benefits?
