>>2414173I am going to say yes, and here is why.
When sucking your own dick, the sensation is overwhelmingly you sucking a dick and not you getting your dick sucked. Sure it feels good, but you by far experience the sucking of the dick moreso than you dick getting sucked.
I would argue that the sensation of sucking dick is by far harder dissociate yourself from than it is to dissociate yourself from giving yourself a handy, so it I would say that if you cannot dissociate yourself from it, then it is gay.
If you can dissociate yourself from it, then it is not gay, just masturbation.
