Nothing seems to have a negative effect on her

I wonder if BC pills are to blame or she is just good at hiding true feelings. She is just as affectionate, horny, very wet during sex and all around pleasant no matter how much -none or IFM or other products I wear. She likes the MX292 smell and A314 + xcite smell.

Extreme doses tried so far:
5 drops A314
5 sprays IFM
Lots of -none from various products
