if he finds these girls hot does not mean that the girls find him hot 
so
so he can only “vent” about his desires by talking to you (which is childish….like a kid talking about smth that excites him so much)
does he have male friends? If he does he can be asked to discuss it with them if it bothers you (and it should bother you) 

also he is almost 40……last chance to be attractive to younger women…be a playboy… 

since he behaves like a child talking to him will not make him change (but you can try  - no harm in that)

I would make him jealous instead….and not with a photo….
you are much younger than him so in your relationship he should be scared to lose you

let him notice you talking to a hot guy (hire a friend, far relative)
then come to him laughung and happy and say
Jack (or Bill) said I look sexy in this dress…do you think I look sexy in this dress? (ask with naive eyes)

If you ogle other girls AND ogle your girl, for goodness’ sakes, let your girl know that you find her attractive!  Society does enough to make women feel inadequate.  Most of us (not all – some of us don’t need anyone’s approval) at the end of the day just wanna know that YOU think we’re hot, or sexy, or smart, or endearingly kind, or anything else you admire.  And we wanna know that you can like those things about us WITHOUT comparing us to someone else in the same breath.  “She’s smoking hot, but you’ve got pretty eyes!”  See how that doesn’t really feel like much of a compliment?  You might be thinking, “I told her she’s got pretty eyes - that’s gotta stick out to her!”  No.  Instead, we heard the “she’s smoking hot” part and wondered if we were the consolation prize.

I apologize if I sound kinda bitter.  I’ve been in these situations too much.  The trouble is, I constantly think I’m finding a nice guy (he listens to me, he holds conversations about real-world things, tells me about himself, he asks how my mother’s doing, says he’ll meet my family, etc), and then over time little things add up.  But when you notice them, you’re told you’re being insecure.  But it’s a trap, and then you’re stuck because: you feel hurt and disrespected, yet you feel like you’re too picky, sensitive, controlling, etc if you say anything, let alone try to break up.  If he can’t even have sex with you without a) talking up another woman ad nauseum before, during, or after; or b) watching porn before, during, or after, you’ve gotta wonder if he’s not just using you for something.  More appropriately, if you’ve told him it bothers you and he keeps doing it, you’ve gotta wonder if you don’t deserve to be happier somewhere else.

The biggest flaw I see in his beliefs is that he thinks modern marriages fail because they don’t follow this restrictive behavior. As far as I can tell, he is basing “success” and “failure” on divorce rates, which have increased over the years.

In the past, there was a huge stigma against divorce and divorcees, which kept divorce rates low. The problem with this social stigma, is that it trapped many people in marriages which were filled with domestic violence, a problem which was never socially acknowledged.
“Over the Threshhold: Intimate Violence in Early America”

If a marriage contains domestic violence, I would not consider it a success. Since this isn’t an issue in Mike’s marriage, he doesn’t seem to consider the possibility that many of the marriages in our grandparents’ time should have ended, even if they didn’t.

I would equate Mike’s restrictive behavior with a preventative mastectomy or preventative prostatectomy (one that’s performed proactively to prevent breast cancer or prostate cancer before it occurs). In rare cases, the risk factors may be high enough to make it the healthy choice, but for the majority of people, it simply creates unnecessary consequences without a corresponding benefit.

My girlfriend and I are both active in the local dance community. We socialize and dance with members of the opposite sex without creating any jealousy or distrust in our relationship. There are married couples in the dance community whom have been together for decades. This hasn’t created a problem for them, despite the constant interaction with members of the opposite sex.

Jazz’s husband is being boorish and inconsiderate of Jazz’s feelings … and the latter is a problem. Some of my behavior toward my girlfriend (when we’re in private) could be considered boorish, except she enjoys it. By engaging in “boorish” behaviors which she enjoys, I’m being considerate of her feelings.
