I met my girlfriend while wearing MX115 and it led to a similar situation as you except it was on a chaise lounge at a pool. I really liked her but she freaked out after she thought about what had happened and wanted to keep me at arms length. She really liked me but she couldn’t understand why she felt such an animal attraction. Because of how quickly things progressed the first night we met it was as if she’d reached the end of a rubber band and snapped back.
It took me being witty and charming and avoiding wearing ‘that damn sex cologne’ for a while (Anything akuto scented she couldn’t resist but I was wearing MX115/MX116 around her.)
I backed off and switched to P96 and my Grapefruit scented ICM 1a and she came around very quickly. Now she sees me as a great guy, boyfriend material and yet someone who can still tear it up. 
Short answer, bathe in P96 whenever you see her. It won’t hurt matters. 
Good luck!
