Guy's Behavior

What is your perception of a guy who brags about the women he can hit on?

Becauase he believes he is a stud? Are they immature guys or what is the perception of you of these type of men.
What is your opinion on this male cousin I have, is he just bragging or that is a sign he will become a dog and treat women bad in the future.

I have a 20yrd old cousin. He is good looking and he is very much into working out and for his age he has now a ripped chissled body, he is kind of addicted to exercise. Anyway since he is family he had always find in me like a friend he can't confide in telling me personal stuff. He had been like that for many years. This cousin had always believe he can get all the girls he wants. Since he was like 16 he tells me he has a thing for older women and even when he was 16 he already knew about sex, fuk**ing, sex positions, etc. When he was younger he always like to tell me his stories and always tell me that the mothers of his high school classmates always chase him and he had had sex with them at his young age, even when he had a girlfriend (around his age) he dates and he supposedly he loves and care, according to him, he was getting laid with older women in secret. He had even had made passes at me before but I had put a stop on him so he no longer bother me on that field, he said I im very attractive.

Yesterday he texted me and told me I have to tell you something so I let him tell me what it was so he told me: Three or 4 years ago I had a small fling (when he was 16) with the mother of a former high school classmate and you won't believe that this mother started to follow me on Facebook two weeks ago and this past Wednesday she invited me over to her house and guess what? I went to her house beause she insisted me to go and see her, that we could take advantage that her husband was out of the country and well.. I end up going and we ended up having sex"

My cousin now is 20 years old like I said he has a nice tone chissled body and his photos on Facebook are of him shirtless and showing his body., But guess what also? My cousin has a current girlfriend for one year now and the times i had seen him with his girlfriend in family get togehters that he always invites her, they behave like a couple, making out, hugging, they seem to be"in love" or puppy love (LOL!!) but on the side and in secret he is supposedly getting laid with older women.

Is this behavior will stop beacuse he is just young and experiencing stuff but as he grows old that immaturity will stop or he is a person who need to be watch out seriously from now on as he could become a man who will make suffer all women he will be involved with when he is much older?
