Cumming from penetration? I thought my friends were just making things up!

Yeah I can't get off that way. Not for lack of trying. My friend instantly had no trouble when she started having sex. Different people need different things. I can only get off from direct stimulation to my clit. I mean it feels great from just penetration, but it can't get me off.

I've had guys get frustrated that it also takes me a long time usually to get off. It's very rare that I can cum in under 20 minutes. Whether I'm in control or someone else. Other people that I know however have multiple in that time. grr.

So the point... It's just how your body is. If he wants to take the time and learn your triggers I'm sure he can bring you to have many more. There's nothing wrong in any way. It's pure biology. I'm sure it all goes back to the fact women are designed to take longer, so that they orgasm after the man, to increase chance of pregnancy. Something about the muscle contractions help to move the sperm up... I haven't taken anatomy is a while.
