If I may throw in my own opinion in here for no reason beyond spouting some random words in what seems to be a seemingly long forum rant on "sex is bad" and "no it isn't."
Sex isn't bad. Sex is amazing. Love isn't bad. Love is amazing.
However, both can backfire very very easily.
They should go hand in hand with each other, and one should not be without another. My first girlfriend was rather awkward, and so was I, and we never did anything beyond kissing and 2nd base, so eventually we got tired and broke up. My 2nd girlfriend knew exactly what she wanted in a relationship. Someone to love, someone to fuck. We had both, but it still didn't work out, mostly for entirely different reasons which I won't go into.
Sex isn't something that people should badmouth. It's a great experience, and it's not just a thing that guys want all the time. I've met women that enjoy sex just as much as Average Joe Frat Guy. People in relationships should talk about sex, and if one person (either person) absolutely wants nothing to do with sex then the other person (call me shallow, I don't care) should consider leaving if it can't work out.
From my experience, sex for a man is a release. It's something we naturally need to do. Either from intercourse or masturbation. We build up testosterone, become overly callous and a way for us to balance our crazy antics, rage, stress, and everything else is to have sex.
Now sex for a woman? To be honest I have no idea what it means for a woman. I've heard thousands of different opinions: Like a guy, it's a release. It's something fun to do. It's something they hate to do, but do it to make guys like them. It's something that can be addicting. It's something that should be shared only rarely. It's something they only share with one person. It's something they share with lots of people. It's something to try on both men and women. It's something they do to take control in a relationship, or it's something they do to become closer to their significant other.
So lets say, sex for women is different for every woman.
And sex for a man? Well, I have yet to hear of a man tell me anything different about his experience with sex. And mine is pretty much the same as well.
Don't put sex off as a bad thing. Try it. Be open. If it isn't for you, then don't do it again. Simple as that.
