Hi, I would like to ask for something I've just experienced but have never experienced before.

My gf and I were trying new ways to pleasure each other, making the story short, she put lots of lube on my penis and started stimulating the tip, literally only the tip, like where the urethra is. She began rubbing the palm of her hand in a circular motion there. Have you ever felt you were being stimulated and the "road to orgasm" suddenly strayed and you were like in another road? Like it's just too much stimulation in an instant and feels weird and so not under control so you have to ask for a stop and then go again thru the normal road? Well, this time she didn't stop, she followed thru rubbing and rubbing until I felt... I'm not sure what it is, it's like being light headed and have a tingle in my arms, it stopped being uncomfortable in my penis, it just was what it was. I'm not sure if my body ever felt that way, even my chest felt different. Neither I'm sure if it was a comfortable sensation, but it was something interesting, we did that twice.

Do you happen to know what was that? How to call it? Was it safe? Should we add that to our repertoire? Have you or your partner experienced something like that before?

I'm reading you all, thank you!
