Why did my husband go to a strip club, lie about it and brag months later to a friend about his experience?

I saw an email from my husband yesterday bragging to a friend about a mancation weekend he took with a friend to a football game in another city and boasting with the phrase "remind me to tell you about my Double-mint Twins experience. This trip was 11 months ago. I was fine with him going, actually encouraged it because all I thought he was doing was going to a football game, having beers, etc. I am so appalled, shocked and hurt. He obviously was never going to tell me about the strip club--obviously if I knew he was going I would have had issues with it--and now still swears on his life he didn't have a lap dance. So what am I supposed to make of this Double-mint Twins experience statement, and the fact that he's boasting about it 11 months later? He says that they were dancers on stage, and that he didn't have a lap dance. Oh, and the fact in the email that he talked about another "mancation" and that this guy should go the next time. Obviously this wasn't going to be the last trip and sounds like I was always going to be in the dark about what really happens on these trips. I am very hurt. I have a really good body, we have sex all of the time, etc. Now am I going to say I never nag at him, no. I am not perfect, but we have been together for 17 years, have a little boy and thought we had a pretty good relationship. I feel so disrespected, don't understand why he needs to look at another naked women when he can see me anytime, etc. I work out, take care of myself and get compliments all of the time on how I look. I guess my question is why did he disrespect me like this and go behind my back and do this? His friend is a piece of crap that went on the trip with him, and I have never liked him because I know he's into major porn/strippers, etc. The friend that he was telling the Double-Mint Twins experience to cheats on his wife--my husband says he didn't know this that he cheats on his wife and that he doesn't approve. Seriously, are all men just pigs deep down inside, and I am just now figuring this out?! Not sure I will ever be able to trust again. I am so disappointed in my husband. Now we're going to have to head to a marriage counselor because I am just so devastated--mostly about the fact that he felt the need to lie (seriously wonder what else he could be lying about), disrespected me in an email to someone that isn't a close friend obviously just to brag and make himself look good, and the fact he obviously was really turned on by these girls. Insight? Opinions? Thank you.
