So I have traditionally masturbated with a stroking motion. Today I decided to rub the tip of my penis while using lube. I did this while attempting not to flex my groin muscle, which is difficult to do. Within a minute my temperature went up, I felt my blood pressure rising, and I felt the urge to ejaculate. The orgasm I experienced was quite extreme. I did this another 3 times (after about 15 min or so each time). My question is this: Does this particular form of masturbation produce a stronger orgasm or is it just because it's something new for me. P.S. - I've been having sex for years and years, and it usually takes me around 10 min to cum while masturbating, around 20 while having sex. This was really fast and intense. Such a weird sensation. P.P.S. - The sensation experienced on the tip of my penis while i rubbed it doesn't necessarily feel good, kind of uncomfortable actually. It's like it was extra sensitive.
