Hi guys.
I have practicing for a few months now.
I I'm training, the first orgasm is light, a small squirt of precum and a nice sensation, almost no PC clench, it feels great, maybe not at strong as a normal orgasm. I keep the erection and I try to chain the second orgasm.
That is when I clench. Most of the times is a partial do. So small cum , maybe 1 or 2 squirts. Sometimes I lose a bit of the erection, but I keep going.
I tried with 2 girls and you should have seen their faces,!! Amazing they can't believe it. The great thing is then I can keep fucking for longer. I never went for more than 3 orgasms with a girl. On a solo session I managed 5 orgasm maximum between dry, partially dry and a full wet one at the end.
There is a Czech guy called George uhl, in his 50's he is great at it. He can produce multiple partial DO. Its is a great visual effect, specially with girls. Check him out.
