Well the problem is my gf hurts whenever I try to enter her, she's a virgin, well not really since any form of penetration with a penis is losing it but, she said it hurt really bad, I'm about 7 inches and 5.5 inches girth and I'm not used to virgins.

can't suggest lube or using a sex toy to help(She's very natural and basic when it comes to things) Will only try missionary, she said she wasn't nervous but it was quite..complicated, we're trying again on New Years Eve when she stays the night, any suggestions/ideas on how to help make it less painful for her? Lube, sex toy=no no
