What do you think of a 1st year and 4th year in college dating?

I think it is perfectly fine. If you feel uncomfortable when you and him are around his Friends, ask if you can bring some of your friends so you wont feel like the youngest one their . don't let other people make you so uncomfortable that you start to not like this guy. It's your life, and if they don't like it, they don't have to be a part of it.
