your girlfriend

Nope, does not have reason to jealous or bother you. Especially if she is introduce you to them. I'm studied in school mostly with boys and prefer male friend, conversation for makeup are so boring sometimes. Also when you are with her male friend they really like or hate you, when you are with her female friend, they will be more tactful but not so honest. Relax and try making friends with them. She has chosen you!

my girlfriend is a lesbian haha, obviously as am i.. so if my girlfriend had male friends it wouldn't bother me haha!

Well, I am married. I am also female, but if my husband was to start having a lot of female friends more than male it would start worrying me especially if these are the main people he is wanting to hang out with. Personally too an extent it is expected for him to have lots of friends, and some of them could be female, but never to a point there is ever anything to worry about.

as long as she can explain, why you must be jealous my friend?? you can had much female friend too..right??

friend i have not girlfriend, i am now 50 and may be no any want me.
