There's a type of orgasm I have that I've never heard described, which is the "wombgasm or empathygasm". It's handsfree, and happens when I'm really turned on mentally by something that hits the right note of arousal and intimacy, and I'm able to fully empathise with someone's arousal. My womb starts spasming by itself, pulsing warm pleasure through my pelvis and lower stomach. If I'm in the right mindset this can happen HUNDREDS OF TIMES in a row, as long as I'm mentally stimulated.

It's easier to achieve if I've had some weed edibles beforehand, but I have had it happen when I'm completely sober and either reading good fanfiction or watching loving and passionate amateur porn.

Completely different things arouse my clitoris, completely different kinds of erotica (more kink based) and it leads to a different kind of orgasm too (I can have a mechanical clitoral orgasm without being aroused if I just want to release tension and go to sleep quicker but I can't have a wombgasm without being genuinely aroused).
