I've never been able to orgasm from penetration but lately, the past like 5 times, with my boyfriend I've been reaching orgasm each time he does. I've been with a handful of guys and this is the first time I've ever been able to reach orgasm just from penetration. It's exciting and makes me have the best orgasms I've ever had, even surpassing ones from masturbation. I have no clue what's caused the change, but I love it. Has anyone else had this experience ?
If, as Aerianne says, you are relaxed enough, and also in a frame of mind where you truly want to give yourself to this person, then yes, it can & does happen. Great sex is just as much a state of mind as it is a physical state, you are "in the moment", he is probably stimulating your Gspot (without realising it), you are in a receptive mood, so bingo! You have an orgasm!
Relaxation is the key and being in the moment. Some of the most intense orgasms have come (no pun intended) when I am not expecting or putting pressure on myself to have a huge orgasm. I love it when it does happen.
The last girlfriend that I had before meeting my wife, was like this. The first time we fucked, she came before I was even all the way in her and her orgasm was so intense that she passed out! I'd never had a woman do that before and it scared the living shit out of me! I thought maybe she'd had a heart attack or something! Anyway, as it turned out, she just usually had really intense orgasms. Once we started fucking on a regular basis, it was pretty common for her to pass out when she came. It'd usually take her a minute or so to wake up and, to my surprise and delight, she wanted me to keep fucking her while she was out so that she'd wake up to the feeling of me thrusting inside her! More often than not, she'd cum again as pass out once more. One really good days, when I could keep it up long enough, I could put her under two or maybe even three times before cumming myself! She actually seemed to become addicted to it (and maybe I did too.) All I know is that, every time we got together, her first and only goal was to find someplace private and nearby where we could fuck. Tough life, huh?
Sounds to me that you find a cock that fits you perfectly. The best penis for a woman is the one that is wide enough to pressure and stimulate the vagina walls all around, and fill the vagina across its full depth without causing any pain.
