Piper here. It's been a while. I am still with GID husband but have
my own place. I bought it for security and as an escape when I feel like a break.
My husband is always, always denying the gay thing. Long story, but bottom
line is the gut feeling, how he doesn't look at women or ogle them, watches Hallmark movies and
comments on the men, has a gay best friend, is a cyclist and a big fish in a small-town pond. Very southern and 
churchy town. 
While I've never caught him with gay porn or other traditional cheating signs, this is a man who never, ever initiates sex.
He is a big believer in kisses, pecks rather, that are quick and dry. He's kind overall, if often moody.
He rarely drinks EXCEPT I catch him drinking before he has to do his "wifely" sex duty. 
During which time he can maintain an erection and go through the motions, but never opens his eyes. He will not 
look at any part of my nude body, and I'm fit and attractive. 
When we do kiss during sex, he doesn't use his lips like a passionate kiss. Just a tongue, which is odd and yucky.
He'd never admit being gay. He lights up around men and has watched regular porn on occasion. Not gay porn.
Any thoughts would be appreciated. Sending hugs and light to all in this boat!
