100% These men are Bisexual from my own experiences.

And yes its hard to prove, because they are so secretive, and lie through there teeth to hide it, and part of us are that shocked and hurt, we don't want to think we are right, so put up with our doubts, especially if children are involved.
These men become narcissists and compulsive liars to hide there true sexual orientation, not caring who they hurt, and who they might infect with STI's.
They are hypersexual, and avoid at all costs being found out, to avoid stigma, rejection, and discrimination, as many see bisexuality as not a legitimate identity, rather a transitional stage to being fully gay, or simply confusion.
Women and families are caught up in this, without knowing the truth about them because they constantly lie, and try to hide it.They will do anything to not get found out believe me, even offer to take a lie detector test, but know it wont likely happen.

They are always looking for there next gay sexual encounter with a friend, work colleague, some even keep it in families..There are no boundaries for some.

Many Marriages/relationships/families are breaking up, because the man changes towards there women and children in a lot of cases. often mentioning a new male friend, and wanting to spend time with friends, more than usual.

They also use women as a cover, so will often have many female friends to deceive you into thinking they are womaniser's only into women when they are most defo not, this is all a tactic..Once they think you are onto them, they will leave you, and go quickly into an new relationship, making you feel so hurt, and hope you  maybe take them back.


They will fight to try and stay in there marriage/relationship, why because it is the closest thing to normality they will get, but they do not often treat women well, often disrespecting and putting women down suddenly in what was once a loving marriage, and making excuses about erection problems, and wanting sex and intimacy less with there woman, emotionally they are gradually cutting off from women.

They also use hetro women, for money, sex when they cant get out, looking after them as women do, and especially when they become ill.
Which many are getting prostrate problems, and associated cancers.

I know the signs to look out for, if anybody wants to know.

Getting away from these men is hard, because they do the guilt trips, insult you, and try to make you think you cant live without them, knock your confidence.
Yes its hard, but do you want to risk your health and that of your children's, because many have the H.Pylori infection and probably don't know they have it because of constant anal sex with men.

Never allow yourself to do something sexual if you are not comfortable with it, or because you think they will like it or think it will stop them going off, or think it  make them stop with you, because you wont be able to tolerate it emotionally in the end, it will mess your head up.

Its about you, not them..
