Why use a cock ring...
1= My own personal experience in SUCKING COCK is that when the shaft is tied-off at the base (either a tightly-gripped hand, rope, strap, ring) it makes every vein and cord BULGE out... making the loooooong wet gliding of the gently-touching underpart of my lips feel each and every BULGE, enhancing the textures of that FAT tubesteak I've luckily got shoving in my mouth. And we all know, a happy cocksucker is a happy cockpuppy indeed. So naturally, while getting my 'EVERLAST' ( I can get sucked for over 9 non-stop hours ) worked over by a sweetie-pie boner-boy, there are times I'll put the ol' loop around my tallywhacker's broad-base and make everything bulge out farther, make the temperature of my toy hotter from the blood pushing against my skin, and making his taste-experience that much more memorable. (yes, I AM a nice man)
2- The different types i.e. Silicon, steel etc.
2=Again, from MY SUCKING COCKs, I'd have to say the metal ones hurt the teeth; if'n I'm going to the base that is. I prefer the softer ones, though they don't look as nice... and they don't always taste all that jim-dandy, either. I'd go with a strap myself, or a fabric-elastic hairband. Hey Seb, go to the drugstore and buy a multi-sized pac of hair bands - bring them home and arrange them all along the length of the ol' fellow (gates of hell), and if they are tight enough that they make your dick zig-zaggy in silhouette, then cover it with a condom and fuck someone immidiately! Trust me, they'll tell all thier friends and next thing you know EVERYONE WILL BE DOING IT!
3- Why measuring is so important i.e. not too small a cock ring
3=As for the suggestions above, do be careful... your buggerer is the only one you've got (though your partner may have a few dozen of his own to call on, the idea is that YOUR's should be the one he fawns over, TILL THE END OF TIME). If you have some close friends who would agree to gather together and try on each-others' rings and straps and do-dads, then you might find which fits best for you, or... which makes your buddies' dicks perform best for you.
4- How to apply the cock ring correctly and
4=I use the elastic, remember... so after I've been 'up and running' for a spell, I simply stretch over the largest of the sizes in the pac and adjust so the skin of my 'nads feels comfy within the tight-loop, arange it so it looks nice, and feed my meat slooooowly to the lucky lucky LUH-HUH-HUCKY sweetie-pie who is smiling up at me.
(a-hum... bit of a fantasy took place there for a few seconds)
5- Anything else that you may feel is important to add
5=Let's not forget the input of the one(s) that/who are going to be on the recieving end of your TONSIL POKER, and ask what they like. Play with ideas and textures, materials, maybe even make something up yourself/ves. Personally, I've a pair of short-shorts, cotton, acid-green though faded, soft to the touch, did I mention TIGHT? No more than 6 minutes after buying them on a hot day in a strange city at a second-hand shoppe, I had a full bulging erection... what a sight that must have been, huh! But, even better, less than 4 minutes after I achieved full-wood, I was getting m'knob k'noshed on through the thigh-cuff... the cuff being tight it added just the right amount of pressure across the base along the broad-back of my rager... I was bulging from hither to tither and the mouth went WILD on me. Mind, he was a lousy cocksucker, as I'm the type that needs texture, not feathery-gentle... so, I ended up pulling out of his face and since he was the only hungry pup in the joint, I bent it back in and soon went along my bin'niz eslewhere. Yup, that's my two cents worth. Joe
