Hello, I think I've always had this birthmark around my genital area, Just where the Penis meets the Pelvis. For some reason I believe it got bigger, years ago I believe it was just a little dark spot,  It doesn't really itch, except when my pubic hair gets longer.

Well, now I'm concerned, I don't take too much sun, if at all. Can this be something serious? Or this is just a wart or mole that can be removed easily?

Please see pics and let me know what you think, thank so so much for your advise.
