> I find it difficult to make friends with people of both genders, but my hobbies and interests seem partitioned strongly to one gender, virtually making the other gender seem alien and extra hard to make friends with.

I don't think the fact that you find it hard to do so should be a reason to restrict your user-base. I see a case for single-gender outings and understand that some people would prefer such outings, but I think co-ed outings could add to the app.

EDIT: Just saw your link on why tribes are single gendered. I didn't really take the creep-factor into account. Maybe a 2 on 2 female/male ratio would help reduce it, best of luck with figuring it out, it's a tough nut to crack!
