Well I dont think you can get her to like something she really doesnt.? You obviously love each other dearly and its healthy and normal to enjoy different things, including in the bedroom.
No two people are exactly the same and in every relationship there are going to be things that you wish you could change about your partner.
I would just enjoy what you enjoy, let her enjoy what she enjoys and I wouldnt try to change her or force her to be something she is not.
My partner is also not into my panty selling or coming anywhere near me when I have been in a pair of knickers for more than 24 hours, so I do understand where you are coming from.
However, he does accept it because it is a part of me.? I dont expect him to become involved but its still a taboo subject and he doesnt like even talking about it.
He has a love for parrots for example, and I dont.
In my book, if it aint broke, dont try to fix it – but if you explained to your wife just how much you enjoy sniffing her panties and how much it makes you dizzy drunk with an enjoyable high, maybe she might at least let you enjoy your passion.
..Used panties always is and always will be sticky subject because its so controversial.? So if its going to lead you into a fight, keep the peace and dont push it.
