had a second date with this new girl last night that im trying to add to my rotation. It was the first time having (or attempting to have) sex.

Long story short I got performance anxiety right after I put it in and couldn't keep it up (performance anxiety hit me). I fingered her a little but I could tell she was no longer in the mood. neither of us said anything about it and the scurried out of my house in a hurry.

neither of us have said/texted anything since.

so I know girls are insecure and solipsistic she is probably thinking it was something to do with her not being sexy enough or something. so knowing all that should I message her and say it was "nerves" or "been dealing with some family issues and was having trouble focusing on anything else"..... OR should I just pretend nothing happened and hit her up in a few days and try to hang out again?... I don't want her thinking it was her fault, cause I feel she won't wanna come over to 'try again' if she the thinks I don't find her sexy.

TLDR; new girl, first time sex with her, couldn't keep it up (performance anxiety), was awkward, should I text her saying it wasn't her fault OR just pretend nothing happened?
