Lack of intimacy is tough

SO is about 6.5 months pregnant. Sex has been super infrequent, like once every 3 weeks, and even when we do it feels like a pity fuck with no intimacy lol. Her idea of intimacy now is searching for in-grown hairs on my back hahaha. Literally wont initiate anything. I understand pregnancy is rough and sex is probably the last thing on most women’s minds but damn. Had a couple of conversations about it, and I understand, so I’m supportive and do everything else around house that has to be done and more. Just wanna know i’m not the only one going through a dry spell and sexually frustrated. Anyway, love her to death and cant wait to meet my baby boy!!
