At what point do you really HAVE to start wearing magnum condoms. I am 5.3 -5.5 Girth and i can still do fine with regular condoms but i do fit pretty average into a magnum, but i dont feel the need to go only mags yet. So i am thinking that is magnums for 6 Inch Girth and above? My width is about 1.8 ish around their.
