do you actually ejaculate, like you reach orgasm for 30 seconds?
Or do you just feel like your penis secretes a clear fluid when she touces you? If it is, then it is pretty norma. It's called pre-cum. It usually happens when you're really hot. It comes from the cowper's gland. The clear fluid actually can help lubricate the woman if you enter. However, this may contain some sperm as well.

Now, if you reach orgasm by just touching you down there for evn less than a minute, then there's a problem . . .

Not necessarily a problem. You're young and inexperienced so you will cum faster in general. Use other techniques such as by hand or mouth to please your partner in the meantime. Try not to worry about it, and talk to your partner about it so that you don't keep it bottled up keeping you nervous long after you should have begun to feel comfortable having sex with her.
