No need to do anything at all sweetie.

If you continue to feel like this and one day feel the need to act on any of these feelings, then go for it (in a safe way with someone you trust of course) but just because you think you may be bi doesn't mean you HAVE to act on it, if you're not comfortable doing so.

I'm not sure how serious it is with your girlfriend, but if it's pretty serious and you feel you can trust her, perhaps share your recent revelations with her, talk it over and see if it helps to clarify things for you. Women are usually more open minded about such things than guys are and she'll appreciate your honesty.

Don't get hung up on the labels either, hun. Straight, gay, bi.....they're all just words that describe people and suddenly developing a sexual interest that you didn't used to have does not change who YOU are. Putting yourself into a category like that only serves to prevent you from freely exploring the boundaries of your own sexuality.
