Be honest here Frank,it wasn't all night passion was it,probably 30 mins max and then she took you down to the arcades for the night and a ice cream before heading to Chip Alley for some supper,the memories are always better than the realities
You will be judged cometh the day and tbh I don't think that it will go against you,heaven would be empty if you didn't get in because of every little discretion especially if you was young and in love (or so you thought)
