There are corners of the Internet where these are subject of many intense discussions. I'm curious where they stand here.

I've never seen a discussion concernig thigh gaps before. Sure, the gap usually indicates that a person is slim, but that's just it, a gap between thighs is ... a gap between thighs. :)
It would be nice to have one, but that's definitely not a 'must have' thing for me, nor is it something that should be frowned upon. I'm afraid I don't have a strong opinion here, other than it's good to have when it's natural and probably not a good idea to starve oneself in order to get one. Starving oneself is not a 'thigh gap' problem, though, rather anorexia problem.

I wish I had thigh gaps! :'( I only have a little gap but not a big one :(

I'd love to have one myself some day

I've seen such discussions before. To me, they mean nothing. I can't really think of anything positive or negative about them.

So far, no one here has voted for the one about having lots of sex! I've heard of that conspiracy before (it's gone around on Tumblr once or twice) but I don't understand it, especially as I myself am a virgin with a thigh gap.

I honestly wish I had one.

I don't want one though.

Anything below your neck is disgusting and horrible.
