You can certainly have a consultation (and yes, I would recommend you go too, just so nothing gets "lost in translation") regardless of your age. However, be prepared to be told that your ages could be a problem regarding the legality of filing. I believe that you as the petitioner have to be of legal marriagable age in your home state in order to file (be that with or without your parents written consent, as appropriate).
Also, be aware that in order for you to file for him as your spouse, you will be required to show that you meet or exceed 125% of the poverty level and sign a document that says you are willing to support him - not just as your spouse, but until 10 years have passed, he has reached 40 working social security quarters, or he becomes a US citizen. Since you are only 17 and plan on attending college in the near future, I suspect this is going to require that you have a cosponsor - in your case, probably your parents? This means that they are equally as liable financially should your husband decide, for example, to drop out of college and go on welfare. This is a pretty big financial obligation, potentially, and something you should consider very carefully. Check out exactly what's involved with sponsoring an immigrant before you commit to it.
If you are sure that you're willing to take on the obligations that not only go with marriage, but with marrying an immigrant, then from what you have said it sounds like it
may be possible for you to do it. HOWEVER!! Get that consultation, and think very carefully about whether this is the right route to take. As Yodrak said, we really don't have enough info to make that call for you. That's an attorney discussion.
As has been said, it's not necessarily the only option for your boyfriend to attend college here. In order to get a student visa, one must be able to show a certain level of financial assets. I don't know if your boyfriend has that kind of money available (as I recall, one has to be able to show that they can pay for the entirety of their college education), but if he does, that might be an option that would give you both more time.
