Glad I not the only one, although it sucks your going through it. I'm 26 and my daughter is also 4. Usually in the beginning of a relationship I want sex but then after 2-3 weeks I'm uninterested. I'm tired all the time, don't feel good etc and I usually do it anyway because I feel bad, feel like I should, don't wanna deal with the hassle of not.
Having a low sex drive sucks.
