So I am a 16yr old sophomore and i was hanging out with a group of friends at my house, about a hour later one of my friends had to go so it was just me and Cathy.(not her real name) We were watching a movie and a scene came on where this couple were making out, It made it kinda awkward so i pulled out my phone to go on twitter and i was planning to wait till the scene was over.(Im shy) But when i was on twitter she got up, took my phone and sat on my legs facing me. She then began to kiss me and it got pretty intense and this was the first time I made out with a girl (kissed girls b4 but never made out). 

She is really attractive so i got a boner, once she felt it she immediately got off me and stepped away. It was really embarrassing/awkward and she looked at her phone and pretended she had to go cause she was running late for her sister's recital or something like that. This just happened about 20 minutes ago and "Cathy" is in most of my classes, How do i talk to her about the boner accident or do i just ignore it?
