I'm a guy and my best friend is a lesbian. Why would you think it would not be possible? then you are a rare person usually lesbians go for other lesbians and conversely for the homosexuals sometimes you have a transsexual who likes both again somewhat rare occurence this based on sociological and psychological studies in abnormal psychology
As friends sure, but they wont have any romantic interest in each other.
not necesarily.... They could be really good friends, or they could be lesbian. There are other stuff too, like they could be bisexual (a girl or guy who likes both guys and girls) transgender (simply put, a girl who wants to be a guy or vice versa) lesbian (a girl who likes other girls). They could be undecided. Or they could be straight, just really good friends.
Just be yourself, but understand that you can only be friends with this guy.
If she is someones girlfriend and not the lesbian's then she might not be a lesbian. She could merely be friends with this girl. If she is the lesbian's girlfriend then yes she probably is then. :)
You could just be friends with this Lesbian for a while and then she may fall for you, not her current sexual partner.
Not necessarily. Maybe you aren't attracted to that certain guy. If you feel that you aren't attracted to any guys, it could be that your orientation is lesbian. But there's nothing wrong with being a lesbian.
Absolutely not, a friend who gay, lesbian, or bi-sexual is doing what any friend should do and that is being supportive.
If she is a lesbian why would she even go for a guy? Oh yeah she wouldn't.
say "I'm a lesbian, sorry"
no
One cannot be a guy and a lesbian. There is also no "reason" to be a certain gender, sex or sexuality, it just is.
Probably not. They might think you're lucky and envy you for it, but they wouldn't think you're gay.
Only if the lesbian agrees. Is she's a lesbian then she is probably not at all interested in men, do don't get your hopes up.
