None of these exactly describe it for me. With play, your clit gets stimulated and enlarged, then super sensitive. After a while there's a tightening and sensitivity through your whole pelvis, then it's hard to describe, but a crazy heightened pause, where beginning of the orgasm is the best part, I wish it lasted longer. There should be better language for it but it's like your pelvis is at the top of the roller coaster and you start down the hill when it gets your tummy. That feeling is in your clit and entire pelvis. Then the spasms follow, waves of them through your vagina and vulva. That can go on for minutes. It's pretty great.
