Why do some men do this?

Who ia the actress in question?

I think that someone who comments on the attractiveness of a third person while in the presence of their significant other is an inconsiderate ass.
I don’t think it’s “something about men” in particular. Although men may be guilty more often of trying to manipulate in this way, I don’t think it’s something that only men do.
The person that does this does knows that it will hurt their partner, but does it anyway to manipulate them into feeling inadequate and/or jealous. It is a mean thing to do, and I think it indicates a lack of character and common courtesy.

Unlikely the advice will change --- I think you should seek deep therapy -

"Would you ever show your boyfriend or girlfriend other beautiful women or men in real life or tv, I mean would you feel secure and comfortable to do this or not?"

"Hi guys, my boyfriend and I have been together for 2 years and 2 months, I have posted already about another topic, but there is something that I cant quite wrap my finger about and it’s the fact that my boyfriend every time we see a movie, show or whatever on tv and theres a pretty or beautiful woman he acknowledges it and says how beautiful she is in front of me and trust me this is all the TIME!!!."

"....Around August 2016 my now boyfriend as an engineer that he is, started working on a luxurious residential building on the beach where he met this girl that caught his eye big time, he has talked to me about this girl a couple of times now ( last time was February 2020).

So when he spoke about her to me, he always said how beautiful, model looking this girl is, that she had all these rich men sending her flowers etc, and that all the men that lived in that building were after her. He even said she had a coke bottle body , she is slim with a normal body but does not have an amazing body as he claims she has...."

Are you really beautiful and intelligent? Just askin' because you post the same stuff over and over again.

Why don't you leave him if this bothers you so much? If you were 'intelligent', you wouldn't stand for this.

1. I agree with Linkat, seeing a therapist would probably be helpful.

2. A couple in a healthy relationship can discuss how sexy different actors and actresses are. I have no problem with the fact my girlfriend thinks Tom Ellis is sexy (in fact, I might bang him myself if I had the chance). These are things you have to work out individually as a couple,

I personally wouldn't be offended by this.

I dont think its a problem. If my BF said something like that i would just say im better, lol. Seriously, there isnt anything wrong with it.
