I think it's uncommon just because society doesn't really view it as a problem. Hypersexual women are so desirable people barely believe they could exist, and hypersexual men are just... normal. Every guy is like that, men only want one thing dontcha know.
It's the same thing as trying to talk about the difficulties of having a big dick - building a community is hard when every 2nd response is "lel imagine this being all you have to complain about dae charmed life".
It'd sure be great to have a support group, but you'd need the terminator of moderators to keep it from being overwhelmed by losers trying to hit up everyone that posts.
