As Ryan T. stated above, most STPs are the same. I know there’s a dysphoria about not standing to go pee – I have that as well. However, there are pros and cons of using a STP.
Pros – Mostly because they answer that dysphoria of being a “real man” standing and peeing. They can be quick when you want to pee and go.
Cons – STPs can slip, dribble, retain (not fully empty), and can look like you have an erection if it slips out of place or is too big.
There are more that are of an individual’s thoughts and can vary. Some think they are easy to use and some do not. A friend of mine doesn’t use one that looks at all like a penis. In fact, it’s a lid to a Pyrex bowl that he keeps in his pocket and has learned to use without fail. But he only uses it if he needs to.
Me? I have used a few. ReelMagik is one of them. It got wearisome to use the glue to keep it in place. In fact one time, the glue didn’t hold and I found I had wet my pants. I don’t say that to frighten anyone, but it is a reality some (like me) have had.
A couple of things to think about. In the mens’ room, no one cares about you going to the bathroom. I actually had a conversation with a co-worker of mine as I was starting my transition and he stated to me that very thing. No one looks twice if you step into a stall. Furthermore, it’s none of their business. Truly.
I was listening to Sean Hayes speak and he’s not the only one I’ve heard say this, but sitting down to pee is actually less messy. In fact, there are European customs where it is impolite to stand and pee.
Bottom line up front: There is no one consensus on using STPs. Start with the less expensive ones. If you feel you want to go for more and can afford it, then try that. A more realistic one is for your dysphoria and no one else. That there, is the most important aspect of this whole thing. You have to be comfortable with what you do and who you are to you.
I hope this helps.
