Your doctor was not very helpful. Warts can vary greatly in appearance and you need to get tested for sexually transmitted diseases properly, they can't tell just by looking. I hope it all turns out ok. Always use a condom, don't put yourself at risk sexually and never share towels or flannels with anyone, as warts could be transmitted this way. Loiloi x
I've had something similar to that. I had a weird bump really far up the shaft and I too was afraid of having HPV or something, so I got it checked. The doc said it was folliculitis - comes from ingrown or shaved hairs, and yes they grow pretty far up there. That may be what it is, and that bump of mine didnt go away for a few months. I'd ask old partners what diseases they have tho if I were you.
