Have been dating my boyfriend for a while now and whenever we have sex he gets chafing on his shaft from friction (I presume). I am usually quite lubricated, but it does take him a good while to climax, so wondering if that might be the problem. I am going to buy some KY today, but wonder if we may have to go back to using condoms (which he would not like to do). I never feel any pain or anything, just him. Has anyone ever experienced this before? He is slightly bigger than my previous partners, so wonder if that may be a contributor. God, please be gentle with me, am pretty posting this.
