Can't tell if I'm ready or not

Jewel
So recently my boyfriend and I have been discussing sex.. He wants to wait longer and I think I do too, but when we're doing small things(like touching and playing with each other) we both seem to want it really bad. So idk if I actually feel ready, or if it's just the excitement.. How do I know for sure if we are both truly ready for sex instead of just feeling like we are?
