I've been wearing thongs for 15 years, and I just don't feel the strap between my cheeks. I know there's something between my cheeks, but I just don't think about it and I get on with my life. I guess I have my own know-how now, and I try to wear thongs that are slightly loose. I don't like that tight feeling, and I don't want the strap to cut deep into my crack. I know some guys are into that, but that's not for me, and it is for that reason that I avoid g-strings.
