The last time I faked an orgasm, I was 15. He was my first 'proper' sexual boyfriend - I did it once and realised, to my dismay, that he pretty much expected it to happen ever time after that. These days I'm honest. Guys ask what I want, what works for me, they go down on me for (seemingly) hours, they hold back their own orgasms til they're sweating and tense as a neurotic cat, but I still don't fake. I don't want to. Especially with young guys, I found it taught them that all they had to do was stick it in and fuck hard enough or long enough, without the time/experimentation/skill development to actually learn what feels good for his partner. Note that I didn't say learn how to make her cum, because I don't think that should be the goal.
I love sex. I love oral, anal, squirting, deep fucking, DP, hands, tongues and cocks, but I've never cum. It's not his fault any more than it's my fault. My goal is not to cum. My goal is to have awesome sex and have a great time with a friend. That bit, you'd think, would be easy.
