I'm from Europe. I'm a virgin. I tried having sex with my girlfriend, she wanted me to put condom on but it's hard to maintain hardness with a condom on. I have big girth, its 6 inches around, I used Trojan magnums but I compared those magnums to U.S. magnums and their diameter is smaller but they are more flexible. I tried Durex elite at home and, it is very hard to pull on, but when I succeed I can maintain an erection. I still have to try it with her. What are your advises about that situation? Also one thing, I cannot be fully hard with her, I assume that is due to anxiety, I'm about 90% hard, but that's just from foreplay. Should i expect me to be fully hard when we start having penetration?
