one time when i was fingering my girlfriend she said she was close and soon after that she asked if she could finish. i didnt know if i was doing something wrong (it being my first time and all). it kinda upset me. when i asked her about it she said she was just nervous. then another time when i was giving her head (also being my first time) her dad was coming in a little so she got ready to leave. later that night on the phone she said she was really close. and i know if she would have said something she could have finished. when i asked her she said again that she was nervous and i guess i got up to change the channel and she said she didnt know if i wanted to finish her. now is this normal i know it takes longer for girls but by the second time she should have known i want to finish her because i told that upset me. now i dont know if she wants me to do it or not. she says she does but after those incidents im not sure if shes just saying that or if she really wants me to or if im doing something wrong. can someone help?
