Yup, been this way for a while. Stonewall have officially decided its bigoted to actually be gay. How progressive 
People are not attracted to those of the same sex, how ridiculous, gay men are attracted to people who are masculine. Who can be male or female, its the stereotypes that matter, not the sex!
Ditto lesbians. Though given lesbians have spent the past few years being berated for not 'just giving cock a go' (unless they have past trauma, in which case they have a pass for now but should work to 'fix this' ASAP or else they are using trauma as an excuse to exclude penises from their sex life which is WRONG) this is no surprise to anyone. Lesbians should not be vagina fetishists, this is bigoted and wrong. Again, lesbians should be attracted to anyone who is feminine. Screw butches, they are actually men anyway as they prefer masculine stuff 
Bisexual people do not exist at all. Nothing to see here. Naming oneself bisexual is clearly a bigoted attempt to say there are two disctinct sexes, which is offensive. People who formally 'identified' as bi, are not pansexual. And should never say no to anyone for any reason as you must be attaracted to everyone else bigot.
Heterosexual also therefor means the following
A masculine person who is attracted to feminine people, or vice versa. This can be a masculine person with a penis, attracted to a feminine person with a penis. Or non people with penises. Though those people without penises really don't matter in any sense. Unless it is for people with penises to have sex with, then they matter only for that purpose.
