waiting before you have sex

what do you do if you have been seeing this girl for a little bit...you kept doing what she asked...take it slow ....well we took it slow just like she wanted...well last night was the night of truth we got a room had some drinks played strip poker and truth or dare...finely we were in the 69 position she was gushing all over my face...but the sucking on my **** was not very good at all...but I let that go... I pushed my **** in her... I don't know what happen but she was the worst **** I have ever had in my whole life no movements...no. noise no hard breathing hard didn't want to try diffrent position just nothing... I feel you must have sexual gratification during and after sex she had to have *** 4 or 5 times I think she got really wet. now that I've been going out with her for 4 months now I dont want to hurt her feelings but I can't be with someone who has less going for her sex than a blowup doll what do i do
