I don't enjoy sex

I love my husband. I really do and we want a family and we have sex to try but I never enjoy it. I have been with 3 men and with the first 2 I never orgasmed and I have only ever orgasmed with my husband once during actual intercorse. I can get off if he is just pleasuring me with his hand but I dread the actual sex part. I don't want to lose him so we have a normal sex life and I just fake it. I know to some that's a huge no no but idk what else to do. I don't think I could ever tell him. Plus it's not fair to him.
