has anyone ever done this? as in putting their pinky or having a pinky inserted into head of their penis? (into the meatus)........
Yes, Missphatbooty.
The next time you masturbate, work the tip of your (freshly washed) little finger into your urethra and then tickle and turn it a bit. A well manicured nail can even help, so long as you don't push hard. It can be very pleasurable so long as it's not overdone. My lover does this for me prior to giving me oral sex and it makes for a stronger orgasm.
