Mostly for the women out there: Please at least look interested and react while having sex. Any kind of sex. Even just manual stimulation. My girlfriend is just really bad, it's like having sex with a log equipped with a blank stare. I try different things, but she isn't as interested and often just lies back and expects the world from me. Even worse, she is on medication that is known to hamper sex drive and orgasm, so you know, no pressure on me. Boring sex just makes me not even want to try. So please, move a little, moan, smile, grab, scratch (lightly), do something that let's us know you aren't dead. Real men don't need a porn star's acting in bed, but a little passion on your end will make sex better for both partners.

P.S. Be a little spontaneous on your own, suggest something on your own, even dress nice for the occasion (doesn't have to be slutty, but a little sexy). Men try the first two, but I think we can all try all three. Sex is best when it isn't another chore established by a relationship.
