Got couple of drinks and kissed my friend. Am i gay ?

i am guy over 21 and presumably like girls. no fantasies whatsoever about having with guys, but i like to make myself gayish just for fun - like when going somewhere with ladies i joke we all have ladies night out, or sometimes make fun of my guy friends like saying you look y in this shirt and so on .... the other night there was this friend who complained that many have forgotten his birthday and i gave him a kiss on the side for the forgotten birthday. he was kind of shocked he he. is it possible that somehow in my subconscious i'm actually gay ?
