What is the difference between pansexual and bisexual?

The differences really lie in semantics. By name, bisexual means that someone is attracted to two sexes in a sexual manner, primarily male and female. Pansexual means that someone is attracted to all genders and sexes. This can include males, females, trans folks, genderqueer folks, or any other means of gender presentation. This isn't to say that bisexual people don't like trans or genderqueer folks, and that's where the semantics argument comes in. Some people that are pansexual prefer to identify as bisexual because it seems easier, as the term is more well known. In the end, they're both labels that mean relatively similar things, but some prefer pansexual as it encompasses all genders in one term, and some prefer bisexual because it's more recognizable.

Bisexuality is widely defined as sexual attraction to the same and other genders (not just two, regardless of the name!) and pansexuality is sexual attraction to people regardless of gender. The source that explains it the best: http://argentconflagration.tumblr.com/post/67280987324/i-made-a-thing

Bisexual is being attracted to boys and girls whereas pansexual are attracted to boys,girls,transexuals,intersexual ,etch

Pansexual is a new age phrase first of. Bisexual is liking both male and female for the facts that they are male and female and seeing the difference between the love. Being pansexual is loving someone based on love alone and not caring what the gender is or anything for that matter.

It's actually unclear as many that identify as pan or bi just identify with the first term they hear. Many have their own separate definitions anyway. The main ones I understand and have heard are that pan people do not care about looks or gender whereas gender and appearance do play a small part for bisexuals. Another is that bis may have a slight gender preference or even that they do not want relationships with trans or interesex persons (in my case I find that to be transphobic and that's not why I identify as bi). The basic pattern is that pan is a more universal attraction spectrum than bi, but bi is used more as it's the more commonly used term. I personally identify as bi because more people know what it means and I have preferences. My advice is, pick the one that you prefer the sound of and remember that the label is there to help you and not another thing to conform to. :)

Bisexual is the term which says attraction to two (Bi=Two) genders, it's referring to the woman and man (Although sometimes it refers to the sexes themselves (male and female)). Pansexual is a term which tries to break the dichotomy of man and woman and acknowledge that there are more genders and sexes other than that (Like intersex, genderqueers and others) and so gives place to all of them. Pansexuality can be an attraction to a person regardless their sex/gender, or the possible attraction to all genders and sexes.

Bisexual is having attraction to males and female while pansexual is having sexual attraction to all genders.

Bisexual means your attracted to men and women... Pansexual means your attract to men women trans (all genders basically)

Bisexual means that you are attracted to two genders, whatever they may be. Pansexual means that you are attracted to every gender, it doesn't matter.

Bi-sexual is simply when you are a male or female that likes to date and/or have sex with both male and female. Pan-sexual basically means that you have the ability to love anyone or any/and every gender.
