I have never orgasmed. Recently I purchased a vibrator, one of those Bullet things. Since then, I feel I may have had a few "mini" orgasms... I get this warm sort of sensation down there that lasts for about 3 seconds, followed by 2 or 3 contractions and then I start getting really twitchy because I'm suddenly very sensitive and have to stop. I push it as far as I can go, but can't seem to actually orgasm. I'm pretty sure if I had had the real thing I would have known it. Any suggestions?
