These are 3 fundamentally different scenarios since it differentiates "the idea" versus "reality"

First scenario:  When your girl has the hots for another girl, does it turn you on?
Or do you find yourself getting jealous?

Second scenario:  When your girl has the hots for another girl, and she's spending time with her...
INEVITABLY REDUCING the time spent with you.  Do you find yourself getting turned on,
or jealous almost as if she's with another man?

Third scenario: Your girl and the 2nd girl get along well. You think both are hot. They eat each other out for breakfast like how a true Bi should.  Do you prefer that your girlfriend's new girlfriend become your own girlfriend too and maybe enjoy an occasional 3 some?   Or do you find yourself wishing to keep her separate from the relationship with the original girl?

Most of my male friends are wnant-to-be Polygamists. The funny thing is they are very insecure and very jealous of their faithfull SO, and they don't even fuck hookers.

I don't understand what they want ? Other than power over Women, they don't like when I make fun of them, about that.

Why worry what she's doing while I'm sleeping  ?

Jealousy clouds reality , drains time and energy , while  adding clutter to
your mind .
Jealousy is an unnecessary emotion .

 Sound sleep is very  important for mental and physical well being  .
 I spend  too much time sleeping  after a three some .

When it's time to rest, I can fall asleep in five minutes .

  Good night .  

third scenario for sure..she has loads of bi friends..she loves it both ways..who am i to argue..threesomes are always available..i never get jealous..i like to watch..i can always join in at anytime..there is always no jealousy involved at any time..it makes for a healthy sexual relationship where everyone gets what they want anytime they want it..you cannot ask for more than that..

My SO is bi, and we often do 3 somes with her friends and I love to watch them while masturbating.  I finish up by coming all over them and they love that.

Well can't say I've been there yet.

With that said, with the right one.  1 is far better than 2, 3, 4 or more.

i am not bisexual, but i have bisexual friends of both genders and they all have to deal with ignorance and stereotypes like the ones perpetuated by the OP. just because you are attracted to both genders, does not mean that you will or even want to actually engage in sex with anyone outside your SO. as a straight man do you feel the need to poke every female you see?

Did it dawn on you after typing that, this is the reason most guys are here?

Insert the word attractive before female into that question and the answer is yes.

If I am not in a comitted relationship, my genetic make up compells me to poke every attractive female there is......

and your point is? What? gf60
