I've never had an orgasm before, and I'm wondering whether now that I'm finally learning how to masturbate, it's happened and I'm just not realizing it. At a certain point, when everything feels really good, it feels like my vagina (and inner parts) hiccup repeatedly, rhythmically, and involuntarily. Afterwards, my bits continue to randomly twitch for about ten minutes or so, or at least it feels like they twitch.
Am I having an orgasm? I'm not having those toe-curling sorts of sensations that everyone seems to talk about, nor do I lose control of anything (except for the parts having involuntary spasms).
Thanks in advance!
