Im a male trying on several black leggings for running, stretching and cycling, I've never bought anything so tight. Im skinny built and have tried new balance, asics and adidas. My questions:

I've read some more expensive leggings have not a single, but double seam at the front side (crotch), whereas most simple leggings for men and women have just one seam in the middle. Should I return the leggings I bought and buy only the ones that have 2 seams at the front to better accommodate my manhood bits? I’ve also seen that expensive adidas leggings have just one seam at the front so, maybe I’m overthinking this?

Im not going commando or wearing sport shorts over the leggings because it doesn't have any purpose, except to drag you down when running, and look unflattering, even my boxer shorts make it look a big silly, because people notice them on my leggings, so I’m thinking about buying a thong, but I don’t know what brand to look for, if cotton would be better than polyester or if I should buy a V string or a G string.

The adidas I bought are cross high waist and are for women, however, I don’t see why I shouldn’t buy them: they sit good and aren’t too tight on the waist (seller told me leggings for women are wider on the thigh and smaller on the waist, but to me they look and sit good and the knit is softer than the other ones I bought, I like them. Am I going to regret keeping them?

Any other tips you have, welcomed.
