pansexuality is when someone does not base their sexual preferences on gender (aka he, she, they them, ect...). instead they get to know someone for who they are ....beyond their gender..... common interests, whether they are fun to be around and share the same life style and personality (personality as in what they say and do, not in the sense of a personality disorder)

Example a woman who is pansexual may go to an event and be attracted to the key speakers not because of their gender (he, she, they them ect..) but rather because the speaker appears to be a good person, living a good life and share the same common interests.

Bisexuality is when based gender a person is sexually attracted to both that good looking guy over there and that beautiful woman over there. when actually engaging in sexual activities they enjoy "it" with both .....genders.

homosexuality / gay/ lesbian is being sexually attracted to and enjoying sex with people of the same.........gender..........as their self. intimate relations with other genders or orientations just dont interest nor "do it" for a gay or lesbian person. I am lesbian and I have tried intimate relationships with men and it just doesnt get the job done nor does it hold my interest, nor am I attracted in any way to other non lesbians. I am happily married to my wife.

Asexuality is when someone does not get sexually attracted to any gender or orientation. physically they do not have the interest nor the physical attraction, nor the physical responses because their body does not have sexually activating endorphins and sexual responses. they dont think about sex in terms of liking or hating because their bodies and brain do not physically or mentally respond to sex that way.

Transgender is when one is born with one gender but because of many situations, mostly physical are actually the opposite gender and sexual orientation.

Another term that gets mixed up is celibacy. This is when a person regardless of gender or sexual orientation purposely chooses not to engage in any kind of sex. This can happen just as a healthy choice or because someone has been harmed through sex and now they have problems with engaging in sex acts. There was a time because of my being an abuse survivor that I purposely said no to sex, hand holding and so on. may with PTSD and other disorders related to abuse go through a period of time where they purposely avoid engaging in intimate relationships.
