Wow pinkie, that's up close and personal... definately wasn't expecting that when i scrolled down!
CW22, please, never be embarassed when posting these kind of questions in Ladies Lounge... us gals love to gab, especially about sex and particularly about orgasming!
-Yes it is possible to orgasm from intercourse, but some women have more success than others. Personally, my chances of getting off increas 10 fold if i'm on top.
-If you've had an orgasm, you'll feel great! It'll feel like your whole body is pulsating and the strongest point is in your groin area. You will feel your muscles clench up but that makes it more intense! Don't stress if it takes a while to get used to orgasming.
I found masturbating made it a lot easier to figure out what i liked and didn't like and that helped make communicating to my partner what worked and doesn't work.
As far as duration of sex, it should go as long as you both feel comfortable. If you're 100% satisfied with 3 minutes of penetration, then that's wonderful. I don't know many women who will orgasm in 3 minutes of just penetration though. (Just a heads up). If you want hours of sex, then that's another story altogether.
When i masturbate, most times i'm already in bed, just waking up or just before i go to sleep because those are the times when i'm most wanting it. I agree with Shanifaye, if you feel silly just on your own, buy a toy. A small bullet runs about $20 Canadian, and the people at the adult stores are VERY helpful and VERY understanding. Don't be embarassed by them. OR, order online. They deliver most times in a discretely wrapped package.
Good luck! Hope things go well for you!
