Huh? You can call a gay person a gay guy or lesbian woman. Except if they are transgender, then you call them what they prefer to be identified by.
Here's a hint, they're not a snake, you can ask them what they would like, that's better than guessing how not to offend "them". It's okay, they won't bite. Unless you want them too :-)
There are 3 layers:
Sex : Your actual physical body, male, female, other.
Gender : Your identification of male, female, transgender, none of the above.
Orientation : Your preferred sexual orientation, straight, gay, bisexual, other.
Remember that for gender and orientation (and sometimes sex) there is no "either this or that".
For example, it is possible that some of us are more bisexual or less bisexual than others, more straight, more gay, less gay, etc... It's simply a continuum.
