Accept that you are learning and don't take what partners say to heart. Hopefully you have a tolerant partner. If not, don't let what your intolerant partner says get you down. Now I need it desperately enough to want to cheat on my 4-year hubby. With women, it is interesting.
Women have low sexual desire regardless of what age.
Then all of a sudden something happens where they become sexually stimulated, maybe by a huge attraction to someone. Maybe you are now experiencing erotic fantasies or got turned on by a certain book or movie. You can make sex with your spouse more exciting by using your desire with him. They say women as they get older get more into sex. I think it depends on how women think.
