So I am planning on marrying my girlfriend, but we agreed not to have sex before we are married. The problem is, I am somewhat hung, and she is fairly small. I am about 3.5 fingers wide (and I have big hands) and about 7 to 7.5 inches long(erect, of course). I can hardly insert 3 fingers in her currently, she is very tight... I know the first time is always a bloody mess, but I am honestly afraid that I could cause her some serious damage. What should I do?
