Molluscum is a different virus, so you're right that it's unrelated.
Your girlfriend may have contracted HPV from any previous partner. You may have HPV, but inless you have or get a visible wart (usually on the shaft, where you can hardly miss it), you can't know if you have HPV, and besides there's nothing to treat.
There's not much to say to subsequent psrtners. You don't know if you have HPV and there's nothng to do anyway.
If you get a bump on your shaft, check it out.
Best.

hope I go more often to the doctor and take care of myself. People often read or hear stories like these and think it will never happen to them (that use to be me), but they have to be careful and use protection because sex is not a game. I now wished I was careful. Now I will always wonder why it had to be me.
