You are beginning to sound familiar. I think we have exchanged views before, you under a different name. Just because pretending to be heterosexual worked for you (but does it for your wife?) does not mean it is the way life and marriage are supposed to be.  Yes, many marriages become sexless after the children are born, but that is so very sad. MANY many couples enjoy sex as long as both are physically able, often into their eighties, even if intercourse is physically difficult.
