I read this recently, written by a man.
Foreplay doesn't star in the bedroom.
It begins the moment you wake up.
It begins when you stretch over and kiss your wife/partner and say good morning, before holding them in your arms and stroking their hair.
It then continues as you bring your wife coffee whilst making her breakfast and getting the bathroom ready for her.
It continues throughout the day when you phone/ text her to ask how her day is going.
It continues with you cooking for her without asking first and cleaning everything away automatically.
It transpire as you run her bath with her favourite bubble bath and soft towels laid out for her.
I hope you get the drift.
I'm sorry but my Stbx and I had a similar relationship to yours, until it dawned on me how much I resented him for the fact I felt like an unpaid cleaner and nanny.
As we were on the verge of breaking up I told him what I needed. I wanted to feel special, I wanted to go out for dinner and be the one he put first, then I would feel less like a domestic slave and more like a sensual woman.
Though he agreed with my suggestions and tried to make it work in the end he couldn't do it.
Sex with him became like another chore, a tick list even. Washing done, ironing done, cooking done, washing up done, sex done.
I am now with someone else and the sex is amazing, I orgasm every time (sorry to be blunt). I miss him when we aren't together, i feel like a sexual woman with him, something I just didn't when with my ex, no matter how much he told me I looked great, actions speak louder than words.
I feel so much more than just a mother and home provider now.
This is probably not what you wanted to hear but I am giving you an honest view.
