ill tell you what you need. Fencing cups. when i use to fence[yes i had all the gear] there where a few women there and the used this round disc shape to cover them up. They was padded round the side so it wont cut into u or iratate[no i havent tried them on].
Have a browse somewhere to orded them. Dont think they will be that much.
Still, there's a 1000 and 1 fencing suppliers in the US - just whack it in a Search Engine. I know of 3 in the UK, and one of them sold a blade that snapped after two weeks and nearly skewered my arm!
Dude it's your call.
personally i don't thimk it's worth it, but each to there own.
Any way being shot in the nipples, balls or the adams apple are the most painful places in the world.
