My advice would be not to get into a relationship or get married if this is the way you are wired. Unless the women you choose to be with holds exactly the same views as you.

if you find someone who understands exactly where you are coming from and you both start the relationship with a clear understanding that meaningless sex will occur and both parties are aware of this then there is no issue.

however if you get in a relationship with someone and they dont know what your intentions are then this would just be cruel and i suggest not starting the realationship atall.
