Im a 19 year old girl. I've had lumps on my butt for as long as I can remember, that's why I don't think it's an std. They're always there, but they come and go, sometimes its worse one day then hardly anything the next. They are soft to the touch. They don't pop. They aren't really painful. They are just really, really unattractive. If I mess with them they'll get worse (swollen/bigger). They are red/pink. Sometimes Uncolored. Occasionally I will get one or two hard painful ones that eventually I try to pop and blood and a little puss comes out. Those really suck. I'm only a little bit over weight. Healthy. No other skin problems. I'm just getting sick and tired of it.
I thought I was the only one! Well I'm not sure what it is either, but I don't think its a big deal.
