having sex for the good of the relationship

DISCLAIMER: I don’t mean non-consensual or obligatory sex at all. Men do not have a right to a woman’s body just because you’re in a relationship. I am a woman and I do think of myself as a feminist.

I was just wondering what people in general think about the idea of having sex even if you don’t necessarily ‘feel like it’ for the good of the relationship because you love your partner.

In my experience, my sex drive isn’t that high and I don’t get an impulse to initiate sex very often. It’s not because im not attracted to my partner or don’t enjoy sex, I think im seriously just lazy and need to overcome that to keep my relationship strong. It’s like, when I do have sex with my partner I almost always enjoy it, the idea of it just doesn’t sound good beforehand. Separately, I also notice that if my partner and I have not done it in a while, our relationship gets worse and we argue more, etc. So when I realize it’s been awhile and I see an opportunity, I’ll just initiate even if I don’t really want to in the moment. Or if he initiates and my first instinct is no, I’ll think about why im saying no before I respond. If there is a legit reason beyond me being lazy that I don’t want to have sex, I say no.

When I read dead bedrooms posts or talk to friends in bad relationships who tell me they haven’t had sex in 3 or 6 mos or whatever I’ve wanted to bring this up and ask if they’ve ever thought about it like this but I worry this is some weird internalized misogyny or patriarchy thing that im just trying to justify. What do the people of rsp think?
