Almost everyone who hadn't tried it thinks this way. i got a horseshoe ring measuring 19mm diameter and 5mm width and it gives me a great feeling during intercourse because of its movement. it's the same for my gf, she also enjoys this movement very much.
It is surely a hard decision to get this sort of piercing, but i think it's worth it. i got mine 3 1/2 years ago, and i would never put it out. and in my oppinion, it doesn't get in the way while Penis Enlargementing.
