Really angry with girls who claim to be lesbians and then sleep with men, such hypocrites?

they are this glorious thing known as bi. or pan

They only tell you that because they don't want to sleep with you, I haven't had that problem so I can't say It makes me feel angry.

Is there an actual question in there somewhere

Bunch of nasty demons

According to a recent study, girls are ranked the following when it comes to sexual-orientation.

Straight

Bi-Sexual

Lesbian

When it comes to men they are ranked by the following:

Straight

Gay

Bi-sexual

As you can see, girls are more likely to be fluid it terms of experimenting between the two genders.

Problem is that so many people think a person is either straight, gay or lesbian, when a whole lot more people than are gay are lesbian are actually bisexual and enjoy sex with both sexes. But people label others as "gay" or "lesbian" and seldom as "Bi".

What business is it of yours? There are no rules that say lesbians can't sleep with men or that gay men can't sleep with women. Many do and it doesn't change their sexuality.

Is it really your business though?

What some else is doing that is their prerogative that you cannot control invokes anger in you? Let's see how long your sanity last while they will still be doing what they do.

Why angry? Is this a cause for anger? Do you anger a lot over trifles? If you are not in a relationship, it really doesn't matter at all to you, does it? If you are in a relationship in which you pledge fidelity and you don't honour it, then yes, there might be causes of anger around this, but no more so than with infidelity among heteros or any other sexual orientation. If you get angry at something like this you will probably not live to old age.
