Just posted in another thread about this. At 8x6.25 I found the XL snug and difficult to keep it all the way to the base … perhaps someone should make penis garters (I want a precentage if anyone does it). Anyway, The contempo Wet-and-Wild works at least as well as the XL and has greater sensitivity.
That said … 7-1/2 girth may be a bit beyond what that condom can do.
