Is it normal to have rapid convulsions during sex??

Seems to me like you are having amazingly strong orgasms. I have to say, I am a little bit jealous!

I have been having sex/foreplay with this girl for a couple days and as someone who views sex as good only when the partner is pleased, it was one of the most hottest and self-gratifying moments i have ever had in the bedroom. A huge turn on. If she doesn't shake every time after sex I don't think the sex was good. I'm just a natural pleaser man its how I get off. Now I only wish I could do it with my dick. My foreplay game is strong my dick game is kind of weak tbh. I need help. Any advice?

It's completely normal, and I can even tell you why it happens during sex and not typically during masturbation. There is a psychological response taking place during sex that is triggering the true emotional and physical orgasm, whereas masturbation is a physical response alone.

Take Tickling for example, it's very VERY hard to tickle yourself, but someone else can touch you with a fingertip and send you into hysterics.

Same kind of deal, you can masturbate yourself physically, but triggering that emotional response that sets off a true deep full body orgasm can only be done by the skilled hands of a lover.

Your good

that's not unusual.

masturbation often leads to quicker orgasms but when someone else is touching you they're more apt to include your whole body so you may be more likely to have orgasms that affect all of your body, vs just your genitals.

Yep. Orgasm is a series of muscle contractions, that can ripple throughout the body. Perfectly normal.
