Answer:
Sexual orientation has to do with who you are attracted to and with whom you want to have a romantic, emotional and sexual relationship. It is different from gender identity. Gender identity is not related to who attracts you, but to who you ARE: man, woman, intergender, and so on.
This means that being transgender (feeling that your assigned sex is very different from the gender with which you identify yourself) is not the same as being gay, lesbian or bisexual. Sexual orientation has to do with who you want to be, while gender identity is related to who you are.
People who identify as "asexual" do not really have sexual attraction to anyone. They may consider others physically interested or wishing to have romantic relationships, but are not interested in having sex or engaging in sexual practices with others. Asexual people sometimes use the word "as" an abbreviation mode.
Asexuality has nothing to do with love attraction. Many asexual people are romantically attracted to other people, so they can identify themselves as asexual, but also as gay, lesbian, bisexual or heterosexual. Only without feeling the desire to act on those feelings in a sexual way.
