I just grabbed it last night, as a matter of fact.
NOP, you might think this is silly but one of the biggest reasons I don't do it more often is that it makes me feel insecure having to make him hard. Intellectually, it doesn't bother me but, again, in practice I end up questioning whether he's really enjoying it..does he not want me (as I mentally tick off how many minutes it's taking him to become erect, etc). It's crazy. I need to STOP this.
My H becomes hard very easily. For some reason, it takes a while with the JGI. I'm guessing it's because he's thinking, Oh cripes this is the *last* thing I want to do right now. I know that is the most negative spin possible, but I also know that it's mighty close to the truth.
He is unsure of himself during foreplay. Thank you for pointing out why he likes the JGI method. I never thought of it that way.
