Virgin boyfriend…

So I’ve reconnected to an old boyfriend. We dated our first year in highschool and now are about to leave school and are back together again. He didn’t date anyone after we broke up but i dated two guys. Him and I are both christians but I’ll admit I strayed a bit. I’ve done some things below the belt like oral sex, received and given. But I am still a Virgin because I haven’t had penetrative sex. So my old boyfriend I’ve reconnected with wants to remain a virgin till marriage and believes oral sex and all that should be saved till marriage. The furthest he will go is feeling me up under my bra and maybe running his hands over my shorts. I’ll admit it can get a little frustrating but I support his choices. Any advice on just how to stay supportive and how to connect with him on an emotional level instead of having sex?
