What are some non sinful ways to be physically intimate before marriage?

Bobbie

So my boyfriend and I are both Christian, but he is not living his life for God the way I am. I am okay with that, but there is one topic that we have differing opinions on and I’m hoping you guys could help us find a happy medium that fulfills some of his desires but isn’t a sin for me. I’m waiting until marriage, he doesn’t want to but respects my decision. It’s hard for him to not do anything physically though. What can I do physically that isnt sexually immoral? We cuddle and kiss, is making out okay? Would sending suggestive pictures to him be wrong? If he takes care of himself while we’re kissing, is that wrong since I’m not touching him?
