Don't go for it. Do you want to fall in love? Or fight into love? Think about it. With you both approaching 18 and your personalities clashing it's best to end it when it will be least painful. Just think, do you guys think you can go 2 years without having a HUGE fight that will break you up? Just think about how much worse breaking up later could be. He is very immature for being 17, saying he loves but doesn't want to date you (so he can keep his "options" open I assume) and he wants to get around a bit before trying anything serious...and SEVEN guys, that's just stupid.
