Ok real question: if a guy manages to suck his own dick, will his experience be that of one getting his dick sucked or him ducking a dick
The odds are, your brain will focus mostly on one sensation
That depends on the person. Though I feel it might shift part way through. Starting out on sucking a dick, then once it starts to build it shifts to getting your dick sucked.
The odds are, your brain will focus mostly on one sensation
That's my guess.
