Bringing Sexy back

My husband and I have been married for almost 5 years, we’ve been together for 9 years. We have a 13 month old son who is our rainbow baby. We tried for 3 years to conceive him and after a full year of working with an RE, 4 iuis and 2 early miscarriages, we got him 💙 We’re very happy and up until about year 2 of TTC we had tons of sexual chemistry and a great sex life. While struggling though infertility, we lost the magic some. Sex became something we “had” to have and we had to schedule it, but we made it through. I thought that once my son was born we’d get things back in the sex department, but it’s gotten worse. I’ve never been the most sexual person, he usually instigated sex more but I was easily “persuaded” and we had sex at least 3-4 days per week. In the past year, we’re lucky if it’s once a month and I haven’t instigated and I turn my hubby down often. I just can’t get in the mood. I’ve tried to “just do it” but it’s not the same. I honestly feel like pregnancy broke my vagina! Things that used to get me going, just don’t work anymore. I’ve seen a pelvic floor therapist to make sure physically, everything is okay, and it is. I know so much of this is mental but I just can’t get in the mood! We’d really like to ttc #2 but I’d like to get our sex life back before throwing ttc into the mix again. What can I do!?? Is there something to increase libido? I know this probably sounds ridiculous but I’m so frustrated with myself and my body. Has anyone been through this? Help!
