frustrated

I made a deal with my bf that I won't masterbate anymore. The only sexual things will be with each other. Well that was fine but the last 3 times we've hooked up, I couldn't climax. Last night we spent over an hour and nothing. I just got sore and it no longer felt good after all that. I'm so frustrated and pent up that I wanna cry and like I would just do it myself but i don't want to break the rule and Uggg I'm struggling 😅😪
