well no, being bi means you like both
being gay means you like ONLY boys (as a boy)
being les means you like ONLY girls (as a girl)
straight means you like ONLY the opposite gender
so nope
That invalidates the sexuality itself. I understand you didn't mean to, but Bisexuality is it's own individual sexuality and labelling it as half of two is really really insensitive. Thank you for listening, good day
