A person who experiences fluid sexuality will experience changes in their sexual orientation, whether over a lifetime, years, months or sometimes weeks or days at a time.

People who identify as having fluid sexuality often see it as a distinct sexual orientation.
A person with fluid sexuality may be attracted only to men for much of their life but gradually experience a growing attraction to women.

A person may only be attracted to men for a number of months, then experience equal attraction to both genders for a period of time, then experience attraction to neither gender for a time and so on. This would be fluid sexuality.

A term given to anyone whose sexual orientation isn't fixed but changes throughout his or her lifetime. Lesbians and gays think in completely binary terms and believe that any straight person who says this is in actuality a gay man or lesbian in denial however if a woman comes out later on in life having sucked cock for the first 40 years this is completely disregarded. The same with a gay man who occasionally bangs one of his female friends in the ass.
I have a fluid sexuality. I'm attracted to beautiful women AND Hillary Clinton.

Donna was sexuality fluid, she likes one gender sometimes, and another at other at other times, and every now and then she doesn't like anyone at all.

“Sexuality Fluidity”, or as it’s officially known in the LGBTQIA+ community “Abrosexual”, is a sexual orientation where a person may feel their sexual attractions switch between identities. Someone who may be abrosexual may identify with being bisexual one day, and aromantic the next. Because of their sexuality changing so frequently, many don’t wish to seek out a romantic or sexual relationship, but of course this doesn’t apply to all.
Person 1: Hey what’s your sexuality? If you don’t mind me asking of course!
Person 2: Oh! Im abrosexual or sexuality fluid!
Person 1: Ooh that’s so cool!!
