The sad truth is some women just isn’t interested in anything sexual. Could be their upbringing or background maybe even religious but again sadly some women are just cold sexual. Good news is so was I when I was first married. If you read my virgin bride to slut wife history adventure posted here https://flashingjungle.com/terry-webb-virgin-bride-to-slut-wife-history/
You can see even a cold fish can warm up. Dont pressure her. Just romance the hell out of her with nice dinners movies etc. Maybe introduce some porn movies if she is willing. Talk about it and in time she will open her legs to you. Once a women really enjoys herself sexually it becomes a need much like it is to a man I’m sure.
