hey man, what ever came of this? Aside from other slight things I have.. I do get this as well. It sort of feels like an in grown hair type of pinch, its real sporadic, not serious, and not too too painful.. but none the less present.
See a Dr, this is not STD related.
And oh yeah, it's only painful when it gets touched or rubbed or when my boxers rub into it. Sorry, I forgot about that
