I’ve been married four times. Women either want it, or they don’t. If they are in the don’t want it category, all the chocolate, flowers, and massages in the world are not going to make a difference.
Suggestion. Try to think about the last time she was a little slut slut for you. Then when you are cuddling, not distracted, and have some privacy, say... “remember that time we were in Miami. I was thinking about that the other day... I felt just like a young man again, when I’d wake up with a piss hardon, and have to go to the bathroom to masturbate... I was very naughty back then... always thinking about what it would be like to sleep with a sexy woman... like you...”
I talk a lot in bed. My wife loves it. My last ex hated it, and said, “Nobody wants to hear your perverted stories...” So go figure.
