Does She Know Or Not.

I'm literally horny all the time. It's not always possible to fuck my wife and I don't want another female in my life. So I go downstairs to the flat below and fuck a young gay guy called Tommy, who lives with his older boyfriend.
His boyfriend knows and we've fucked him together a few times, but mostly I fuck Tommy on his own.
The thing is, I'm beginning to think my wife knows too.
She's said things like "I'm sure Tommy will be at home in the morning", if I've wanted sex that night with my wife and she's not been up for it. Or like the other day when my wife asked me "If men could, would they fuck only other men".
My answer was "I think most men prefer pussy". But that wasn't entirely true, as I've really begun to enjoy fucking my neighbour.
Don't get me wrong my wife and I have sex a couple of times a week, but I need and want sex daily.
There's also been a development at work as well. One of the trainee's, a young guy (19) called Harvey has been sucking me off when we get the chance.
He's straight acting, but sucks cock like a vacuum cleaner and loves swallowing my cum.
I haven't fucked him yet, but it's only a matter of time, because he keeps texting me picks of his arsehole.
