I enjoy head rings. I have an assortment of them including several black rubber rings in various sizes, stainless steel in assorted sizes, a ring with a ball that is typically used to insert through a PA, and an assortment of those stretchy fabric ties girls use to tie their hair back in ponytails (quite fun around the glans really as they expand and increase the tension on your glans without hurting).
I'm wearing several of them in my gallery pictures and I'm wearing one right now, as a matter of fact.
I don't wear one all the time, but will typically wear one all day when I want to increase my own penis awareness for whatever reason. Sometimes the all-day awareness leads up to a day full of anticipation that makes an evening wank all the more satisfying...and the built-up ejaculation all the more copious.
Sometimes when I have a lot of time (like this past weekend), I'll shave, put on a cockring, add a few more, change them around, experience the different feeling they have with various clothing, go through an assortment off and on, get my balls and scrotum skin really sensitive in the process, put on a glans ring to keep it nicely engorged and then finish off the day with a well lubricated, tightly gripped wank with Albolene that quite literally puts me over the top.
I most often remain achingly but pleasingly tumescent for hours following such activity.
I didn't include them in my gallery photos, but I have a few shots of my tackle covered from balls to base to glans in rubber rings purchased at the local Lowe's Home Improvement Center. 35 in all, I believe, from 2-1/4" diameter on down to the smallest...which is the one around the glans...keeping it plump and shiny. I haven't decided whether to post them as they look somewhat extreme.
I hope others will be equally descriptive of their use of rings...I enjoy reading about other guy's experiences...and I would love to hear from women who's male partners wear them, especially during sex. That, along with the pictures, is why most of us are here.
I'd love to get a glans ring that is more contoured to the anatomical shape of the corona (glans ridge), ideally one that is somewhat weighted on the underside where the glans comes to a "v". Please post a source if you know of any.
Oh, almost forgot to mention, sometimes I use a smaller rubber ring to hold the skin in place over my glans following foreskin restoration exercises. I bought one of the DTR restoration kits as mentioned in one of the Restoration threads and can't wait to get it. This time I hope to continue exercises with the DTR until I have full coverage.
