'My husband is GAY'

I hope some of you can offer some insight on this my husband and I married last year and have been together for a total of six years now and are both in our mid-30s. I think we have a very strong relationshipwe have similar goals, we have sex several times a week (he has a great sex drive, he initiates a lot and seems to be really into it) and he wants to have kids. Hes very loving, physically affectionate, we spend most of our free time together, have a lot in common, stay in touch throughout the work day, etc. In addition, my friends and family all like him and have been supportive of my relationship with him.
