There's a claim that you can orgasm from ANY physical stimulation ie that we learn to orgasm because of various things.
I remember the first time I pinched my dick when I was really young. I thought "ahhhh" that hurt, and it was weird. The first time I had a girl suck my nipple, it was weird in the same way ie a sudden type pain. Nowadays they're much more responsive, but even now, I'm not sure if I've fully worked out how they work.
My lady and I were with another couple a while ago and the woman in that couple could and did orgasm from just having her nipples sucked! This is a normal thing for her. She could also orgasm from crossing her legs together. Everyone is different out there and some get off in ways others can't.
This is possible as I have actually done this.. though it took a lot of teasing, pulling, pinching and dirty talk.. I had the woman eating out of my hand by the time she came.. she described it as a body orgasm which was felt in her pussy as well...
