I so understand!! I am in a r/ship with a vanilla guy who tries this/that but it's soooo ---I dunno....lame?!! I've been with a real Dom and it's SO different and so much more satisfying all around, but then again, there's this feeling that this vanilla guy is more loving, and "nice" etc and you don't necessarily want to give that up.
You are young, and I would encourage you to do what feel good to you. Talk with him, if that doesn't work, fulfill your own needs on your own, however that might be.
