Taping methods.There are probably dozens of ways of taping the foreskin back, but I'll just talk about the most common ones (as well as a janky one I came up with myself).
The "feel cut" method: I call it this because it comes from a pair of images from circlist that call it as such. The idea is to roll the foreskin all the way forward, then put a ring of tape sticky-side out below the glans, roll the skin backwards onto it, tape over the joint, then push the now-hidden first ring of tape backwards beneath the taped joint. This pulls the skin back from the base, stretching out and exposing the inner foreskin, which makes it look and feel more like a true cut cock. The complex rolling and folding kind of implies that you need to have an average-to-long foreskin for this to work. Here are the actual images which describe how to do it:


Getting the right kind of tape and actually pulling off the tricky "pushing the tape back" maneuver can be tough, but with practice I'm sure it can be done easily. Also, where you put the tape and how far you roll the skin changes how tight the result is, so it can take some fiddling. Actually getting the tape on without getting a full erection can be very difficult -- if you're like me, stretching the inner foreskin is intensely pleasurable and can give you an erection almost immediately. And lastly, it might get a bit annoying to tape up your cock every day.
Once again, we growers get the short end of the stick here. This method can work and look (and feel!) great while semi and erect, but when flaccid, there can be enough surplus skin to entirely cover the glans. Worse, since it's the
inner foreskin which covers the glans, this provides no real drying benefits at all.
Good for: showers with a good amount of skin to work with, and guys who don't mind fiddling with tape on a daily basis.
The spoon-tape method: this involves pulling the foreskin all the way back, putting a ring of tape sticky-side out below the glans, then rolling the skin forward onto it, in effect doing something like the spoon method but with tape inside the fold. This doesn't solve the flaccid problem for growers, and can also be a bit uncomfortable as the edge of the tape has a habit of poking the glans or pinching the inner foreskin against the glans.
Good for: adventurous showers? Not my favorite method but maybe it'd work for someone.
My tape method: it's not very elegant, but it seems to work. Starting with the foreskin rolled forward, roll it backwards folded over itself on the shaft (kind of like a reverse version of the spoon method). You'll have a "collar" of foreskin below the glans with the inner skin exposed. Now just tape the joint between the inner and outer skin. Tada! It doesn't look particularly great, but it does its job and even keeps the inner skin exposed as a bonus. It can still partly roll forward onto the glans, but not to the extent of the other two taping methods.
The choice of tape for this method is somewhat important. Generally, the stickier the better, though too sticky and it can become painful to pull off of the sensitive inner foreskin. If the tape isn't sticky enough, it has a habit of working its way off, leaving you with a ring of tape in your shorts. Also, the firmer plastic-backed tapes can poke at your inner skin and glans uncomfortably, so I'd recommend a paper or gauze-backed tape instead.
Good for: just about anyone with a foreskin long enough to roll backwards over itself, unless your penis retreats far inside your fat pad, which can cause the tape to come off.
