Those little red bumps could of been warts, but they could of been completely unrelated and harmless that's why it's very important to get them looked at.
HPV is the virus which causes all warts including genital warts. There are two types, low risk which cause warts and high risk which can lead to cancer. If you have warts, then you have the low risk type.
As they have been there for a long time without treatment, they may prove hard to get rid of. It is thought the longer you leave it, the more stubborn they become. Get yourself to a Dr as soon as possible, it is never nice being tested but it's something we all have to do if we are sexually active. Theres nothing to be ashamed of.
It could be genital warts or herpes. I'd recommend making an appointment with a urologist. Good luck.
