Wellbutrin did the opposite for me. I had no sex drive at all. My epilepsy medication I'm on now though has that effect. My sex drive has doubled in the last couple months. I think it's normal as a teenager. I think it's normal anyways. The only time it's a preoblem is like racee said.....if it becomes an issue with your life or everyday activities. I wouldn't jump straight to meds tho especially if you're a teen. They can affect young people way more and in different ways than people older. If you think it's a problem then talk to a T about it but I don't see anything wrong with it.
