Everytime I have sex (usually happens more when I'm on top) as I'm ridding him I feel a build up of pleasure and right when it feels so good I Keep ridding and then it goes away.. it still feels good but the pleasure build up drops. Is this an orgasm? I feel stupid even asking lol. It's been like this for me with every guy except one time I think the build up led to like a million sensations .. but I was high lol. Any help ladies ?
