According to Urban Dictionary, pineapple penis occurs when a guy completely shaves the base of his penis, and then his pubic hair begins to grow back. In those first weeks after shaving, the hairs grow back bumpy, and "remind you of the pricks on a pineapple, resulting in a pineapple penis."
According to our survey of the state of the American penis, 62 per cent of men trim or shave their privates, with 17 per cent saying they trim, shave, or wax regularly. But pineapple penis is not the only danger that comes with overly zealous grooming: shaving too closely with a razor down there can create painful ingrown hairs, and tiny nicks in the skin which increase the risk of contracting a sexually transmitted disease. A recent study found that 46 per cent of men have injured themselves while manscaping, and 2 per cent had to actually seek medical attention.
"The biggest risks of manscaping are infection, ingrown hairs (pseudofolliculitis), and skin irritation," says Evan Rieder, M.D. "I have seen disasters from guys getting careless with razors and scissors down there. The skin is particularly delicate and there is not much separating the blade from your nuts! Clippers are way safer and decrease the risk of cuts, irritation, and ingrown hairs."
