If an attempt to have sex during a date goes really wrong, how should a couple proceed?

Decision was made to have sex...Unfortunately the circumstances weren't optimal. The woman had difficulty becoming aroused due to where she was at in her menstural cycle and some anxiety. He has a large penis...an attempt at intercourse was made, yet she was in pain and it was stopped. A second attempt was made and only partial insertion could be made...she gave him oral sex, but he didn't climax. Considering these facts (definitely just a really bad mix of circumstances), did this couple "have sex" or not?? Does it make sense to say that the couple did not have sex or was sex had but it was just a disaster??
