Christians going too far? idk what to title this.

I don't know how many of you will be able to answer this but I'm going to give it a shot. Okay so me and my boy friend are in college and we are both christians. And I mean we go to church and pray and stuff and we are pretty devoted but we also like do a lot of physical things, like often taking off our shirt when making out, he has sucked on my nipples a lot, he's gotten close to fingering me but we stopped before it got that far. Well I guess my question is like is that okay? Like I mean we both know we aren't going to have sex because of our religion but is doing everything like up to that point okay? I don't know who to ask about this so any help is appreciated!
