Wow. 29 is very young. And you just got married?

You need to address this. I honestly have never met a man who didn’t want sex all the time (or at least often) at any age regardless how busy they are. There has to be an issue why he isn’t interested in sex: medical, mental, resentment etc

You need to communicate directly that at 29 sexless marriage has to have some kind of reason/explanation. I’d sit him down and have a serious talk. He might need to see a doctor if it’s medical etc Are you planning to have children?
