I must concur with the other ladies....in my experience, men won't cry over the possiblility of spilled milk....I apologize for the horrible pun, of course.....lol...
Honestly, I haven't really felt sexy since before my last pregnancy--let's see, that would be 2 years ago--but the most amazing thing happens. Just when we feel like a gigantic blob that leaks and has mood swings, when we cannot see anything appealing about ourselves--men can. The man that cannot see dirty socks in the middle of the bedroom floor, and will not notice a toddler eating rocks right under his nose.
That same man can look at a woman and see the fountain of life, glowing with energy and flowing with sustenance. Why can we not have that vision....?
Do the best you can--you do have to TRY. That's not always easy, but try to see and feel the energy that your man does--feel the power. Also, he will have to understand that you are genetically programmed to devote yourself to your child, and it takes some time and effort (hint, hint) to flip the switch over to intimacy for a while.
Congrats on breastfeeding your baby. That experience, unlike intimacy, is a limited time offer and you will have that closeness with your child forever!
Best wishes and blessings
