Relationship advice

So me and my boyfriend are both 13 but have been dating for a while and are really in love. We both want to be a little more physical but we don't know what would be an age appropriate step forward. People say there's time for all that stuff and I know but that's why we wanna know what is appropriate.

Edit: a lot of the comments have been about being safe when having sex and that wasn't really what i was getting at. We have only been dating for 4 months and we've decided not to have sex yet and he dosnt pressure me to do anything, what I really ment was what could be something a little physical that me and him could do?
