ok my girlfriend is a virgin.. (shes 19 years old, she never used a tampon, or stuck anything up her own vagina.. nor has she ever masturbated) we tried to have sex twice already but both times we failed because her vagina hole would not let my penis enter.. her vagina hole is quite small.. i can barely force two-fingers in at the same time.. and its super tight.. i can barely get 1 finger in her hole..

- we didnt have lubricant.. is it recommended?
- the vagina wasnt wet enough.. it was all dry.. my penis couldnt enter.

advice please!
