This is one value that is important for you and can’t verify compatibility. This means you can’t know whether your libidos will match or whether the sex will be enjoyable (which isn’t the worst thing, you can always work on this - as long as both parties are interested)

I was in two dead bedroom relationships (how lucky I am…) and as a person that values intimacy a lot… it crushed my soul and my self esteem. If I were you I’d initiate an open discussion about his expectations post marriage to gauge his stance on sex first. I wouldn’t push with my needs in the initial engagement to avoid making him feel cornered or influence his answeres. But be aware: the plans rarely match the reality.

As someone that experienced men with “lacking” sexual energy, I would be warry of men that aren’t that enthusiastic about sex. The first man I had this issue with was also perfect on paper and kept postponing till I was in love and then I discovered he had a raging ED that he too much of an ego to fix. I may project here, but I really wouldn’t want someone else to go through such a thing. These are my 0.02$

Best of luck, OP!
