Low sex drive a problem ?

Well I just turned 18 a couple of months ago, and I did discover masturbation a bit late around 15 years old. But one thing that kind of gets me a bit worried is my sex drive. I commonly here that a lot of guys can jerk off 3-6 times a day. I can only do it once but it doesn't feel that good at all, so I usually wait every other day. But is this something that can be fixed?
