Having a baby is a whole new can of beans. I'm not even sure that it has much to do with breastfeeding. There is so much going on, body issues, new roles, less sleep, many lifestyle changes.
One thing that helped me feel like a sexual human being again, was to embrace the inherent sexuality of my new role. As a mother, my sexuality is obvious, no way could I be mistaken for a virgin. And all that sex I've been having has paid off in a real, tangible way! In the most basic biologic way, the baby is the whole point of having sexuality at all. Birthing the baby, and feeding the baby from my breasts, is a continuation of my sexuality as a woman. It's a spectrum over a lifetime.
Another thing that helped a lot was feeling like my body is a sexy place to live again. Yes it's a baby factory and a dairy, and neither of those things are exactly "hot". Maybe I will never lose the baby weight. Maybe I'll be loosey-goosey down below. Maybe anal is out forever thanks to hemorrhoids. But you know what, thank God my clit still works. And my husband still seems to dig me, hairy legs and stretchmarks and BO and all. Buying a really cute nursing bra, maybe black lace, or something with polka dots (they have both at target) and some panties that fit and have no stains, went a really long way toward making me feel good about sex. For some women, maybe it would be taking a minute to shave or nair, or paint your nails, or an outfit that fits & flatters. Or maybe it could be rediscovering sexy feelings through lingerie, toys, or erotic media.
Also, sex is often a need that only comes second to more immediate needs. When I'm not eating well, upset about things, rushing around too much, or never getting a chance to do things I enjoy, wanting sexual contact goes on the back burner. Similarly, I can't really think about going ahead and trying to have fun with sex as a gift for my husband or to try to meet his needs, if my needs are not being met.
But yes, it will be fun again. Actually, parenting has brought us closer and that has enhanced many aspects of our relationship, including intimacy. Similarly, the changes in my body sometimes seem to work in my favor, with easier and bigger climaxes. And giving birth has made me less modest, less prissy, less prudish. I pushed a baby out, I am no longer concerned with things like farting. We don't get to have sex as often as we'd like, because having a kid is exhausting! But when we do, it's great, and keeps getting better & better. I wish the same for you!
