Blow Problems

So i’ve been talking to this guy and we have been friends for a year before we started ACTUALLY hanging out😉😉 and he knows that i was never happy with my ex and that it was a bad relationship. so when i started making out with him and having fun he would start to finger me which i liked and then i would start to jack him off and give him head and right before he came he made me stop. what. what. what. i don’t understand.
