Is 18 to young or is it okay?

3 years isn't too long to wait. You will still be discovering new things about him every day. I started dating my boyfriend in 10 th grade when i was 15. I'm 19 now and we plan on getting married once he gets out of college (ill be a junior in college), which will be another 2-3 years. That will be a total of a 7-8 yr dating period. You can last ;)
