Amy was kind of right about one thing: sex is overrated. At least in the sense that it's some mystical joining of body and spirit where two people become one and their love transforms space and time and can slay dragons and bring down evil empires. Yes, it can be a wonderful physical expression of deep, passionate love, but it's also a simple fact of our biology, a bodily function like flushing waste and sneezing. It just happens to (usually, and I'm sure debateably for some) feel a little better than those. "Meaningless sex" isn't really meaningless. It can be an expression of yourself as a naturally sexual being. And just because you do not share a profound emotional connection with someone you're having sex with doesn't mean that it can't be an extraordinarily rewarding and in a way loving experience. It's a celebration of having a body, being able to experience physical sensations (mostly pleasure, but for some pain as well), being alive, and having the potential to create new life. It's possible to have some of the best sex of your life with someone you have almost nothing in common with because you only are compatible in a physical way, much like you have friends who you can share musical tastes with but maybe can't discuss your inner feelings, and vice versa. There's so much narrow mindedness and negativity floating around about sex that it's always good to remember it is a multifaceted endeavor with many purposes and significances and that we should all actively fight to promote a more sex positive attitude for our own collective health. f
tl;dr version: It's really not that big of a deal, so enjoy yourself before you're dead and can't jizz any more, for fuck's sake.
But also, you're your own person and have your own issues and it's none of our business how you conduct your sex life, we're just trying to provide some outside perspective.
