Boyfriend masturbating to Facebook friends

Hi I was just looking for some advice... My boyfriend seemed quite unhappy when I was using his laptop to watch TV on, and I wondering why he was behaving so weirdly. Then I (shame on me) searched his history. Sure, there was the odd hit on porn (which I don't mind) but most obvious was the fact that he spends loads of time trawling through facebook pages of girls (exes, other girls and most worryingly my younger sister). This was interlinked with porn, as if he saw the two things as the same. He claimed all guys do this, is that so? And is his behaviour acceptable? It makes me feel deeply uncomfortable.

It is clear that your BF's attention is has been diverted in a negative direction. It should be clearly focused on you leaving you with no cause for concern. I think he is on FB looking for more than just friends. YOU have to talk to him and express your concerns. if he cannot discuss them maturely and curb his actions to a degree that is acceptable to you then tell him to make his FB contacts a reality and politely dismiss him from your life......good luck!
