i'm a guy. first of all, the journey is quite the ride. expect 2 hours of foreplay, and 2 more of intercourse. the guy will plateau, then plateau, then plateau, then plateau, then when things couldn't get any hotter, he will lunge forward interstellar hyperspatial overdrive, causing a supernova explosion. The veil between time and space will be momentarily shattered, and he will be in all times and all places, in celestial oneness momentarily. After his astral ascent, he will return to his carnal form, where he will be weak like a baby, and wet like a chick recently hatched out of an egg. Assume he is vulnerable. It takes a lot of energy to orgasm. Do not ask probing questions, do not hand him the phone with his parents on the other line. Merely offer him a cigarette or two, and perhaps a simple carbohydrate, perhaps some Hawaiian Punch and a buttermilk donut. If you have a hot tub, now is the time to use it.
For a woman, i don't know as much, but they can go on and on, and the don't really hit a peak like they would during normal intercourse. It's not like the shallow breathing, grinding, minute-long, body-intensive orgasm, it's more like a 5-minute, yeah that hits the spot, energy emanating cloud surrounding the body, gentle uphill peaking slope ascending and ascending with no final destination.
Yeah it's all good, take a little g when you get "comfortable", and make sure your with someone you love. It's a powerful experience that has some major positive effects on your relationship.
I've had about 10 O's myself, and it feels like i'm in the DeLorean in Back to the Future and the flux capacitor is running at peak power. BTW, nothing smells better on e than a woman's pungent panties
OK, now i'm giving away too much.
