I have this small, white, painless bump on the left underside of the head of my penis. It almost resembles a blister. I am a virgin so I have ruled out STD. I've had it for quite some time. A few years at least. Its never caused me any trouble but I'm getting worried about it. I masturbate almost everyday if that has anything to do with it. Please help I've looked all over for answers.

They could be skin tags but I am not a Dr. Do they sound like what is described in this article?
Skin Tags (Acrochordons) Causes, Treatment, Removal and Pictures on MedicineNet.com (http://www.medicinenet.com/skin_tag/article.htm)

It can be many things

Reaction from lub you use

The friction plus other issues causes the skin tags

You will find that you need to ask and get professional help ( go to the doctor) since I always use the what if.

If it is something serious and you don't see about it, and I assume you have a lot of future plans for that body part, so you want to see about keeping everything healthy

Also constant masturbation can hurt your ability to have real sex latter, you get so use to a feel a certain tightness and certain movement and then you can't perform unless it is just like what you get used to.

I have a similar problem with my penis, I have had a wart-like lump on the very tip of my foreskin next to the head of my penis. I have had this wart / lump for years, 3-5ish (im not too sure) and since I have not told anyone about it I have noticed cracks in my foreskin and tiny lumps when I pull back my foreskin which I read is perfectly normal. I'm just concerned and it has lead to a lot of depression, I'm always expecting the worse.

Guys, I'm a girl so I don't know... but I know that as a responsible person who is sexually active I go to get myself checked about twice a year.

If there's something wrong you need to go to the doctor.
Wouldn't you hate to find out you could have prevented a worse illness by dealing with the problem straight away?

Sounds like u have some disease!
