Hi, A Couple Months Ago I Had Unprotected Sex And

Hi,
A couple months ago I had unprotected sex and about two days later I noticed a small bump on the sensitive area between the head and shaft of my penis. Didn't think much of it and figured it would go away but after about a week it got a bit bigger and more whitish colored. I ended up popping it and it seemed a small white core came out. I figured it was probably molluscum contagiousum, and since I popped it it would go away. Over the last couple weeks it got a bit bigger again and filled with fluid. It doesn't hurt or cause any discomfort I just want it to go away. Could you help? Thanks
