So, my girlfriend is really tight. Shes a tiny thing. In the past, I couldn't hardly even cum through sex WITHOUT a condom with multiple girls. (only condomless with one) With her, Its a challenge sometimes to not cum too soon WITH a condom. Find myself having to slow down and stop to kiss her and whatnot to take a break but it seems lame. Anything I can do to kinda build up a higher tolerance to her somewhat?
