Is it gay to suck your own dick and get turned on by the sensation of pre-cum on your tongue?
Actually its possible if you are both a manlet and skinny. Probably you can also be slightly chubby, but still mostly manlet. You'd need to be especially bendy from joints if you want to suck your dick when you're over 6'0.
You lay on your back. do a reverse it up, where you roll your hips back toward your head. Put your arms under your legs. Penis is now right in front of your face. suck.
the problem is this becomes more uncomfortable than the blow job feels good.
