Piercing gives me the fear

Well ok piercing doesn't. I've had many. One nipple, one frenum, one pa, and one on the side of my cock on the remains of my foreskin (that was especially cool and sexy looking). So really, piercing is nothing to fear for me.

But this one gives me the fear. This pa, the one i'm getting after I get back from vacation in the next week or so. Not long now! Because this pa is being as much for my wife as for me. This pa is being done in a period of our lives where we rarely fuck, so I won't need to remove it ¹. This pa is the one that will be used to lock up my cock. By the wife who suddenly is really looking forward to locking me. The wife who is these showing ever increasing dominance and more surprisingly excitingly and scarily, enjoyment of her dominance and my torment.

Let's cut to the chase. I suggested the idea to her and I do look forward to it but I am also experiencing my limits being pushed by her more regularly these days, and I'm finding that it's hard. Finding also that she likes, no loves pushing my limits. Hurting me, tickling me, severely limiting my orgasms. Her typical endearment now is a twist of my nipples with her nails dug in, nails she keeps sharp partly for that purpose. She's even been doing it on the beach regularly. Being nice is no fun she says, and she means it. So i am scared to open this door, I like to touch myself, and for her to touch me. I may only get one orgasm a week but I get much more pleasure and more teasing, and when I feel the itch I can edge myself. That will end once I am locked and I know that her love of being mean to me as she puts it can easily lead to long and regular lock up times.

An example. I suggested to her that once broken in i could wear it for a month for us both to get used to the effect it has on us. I have since found out that she thinks if we do that, she will not let me out for my weekly cum, a milking will have to do. Why? Because she can. Cos it's fun, cos it's mean. So you see, though she may never push my chastity limits, she quite easily may and there is no way to know in advance. Exciting it is. Yet I no longer live in fantasy land, or even only half in real life land. I am fully cognisant of what it's like to have my limits pushed for long periods and I know it's hard at times, I have some idea how it feels to be careful what I wish for. I am aware that there is a very good chance that a month, or a year or more from now this thing will become her new tool of choice and I will wonder why I ever suggested it.

Of course I'm a sub with a masochistic streak. So of course I will do it, I couldn't not. But still...

Addendum 1
Of course most people don't need to remove piercings to fuck. Belle and Thumper seem to cope just fine for example. Some women even prefer it. Sandy doesn't, she's very sensitive down there and I've already removed three piercings because none of them suited her. Lads, don't worry from what I can tell this is very rare.
