Me and my girlfriend of 19 months have recently started having sex. However, I could not maintain a full erection due to the size of the condom and the lack of feeling. I'm around 7 inches long, 2-2 1/2 inches wide and have a girth/circumference of around 6 inches. The condoms we used were durex extra safe but I can't find a massive amount of information on larger condoms. The ones I have found as possibilities are Mates Skyn Large, Durex XXL, Trojan Magnum and Trojan Magnum Ecstasy.
Basically I could do with some advice on what condoms to use because I don't want to become a daddy for many many years. My girlfriend is on the pill but I know that's not 100% effective so we just want to be extra safe.
Thanks for any help
