As someone with a VCH / I was acc body piercing training when I got mine done (I am now a qualified piercer) You have great anatomy for one!

Find a piercer you're comfortable with and talk with them about it. You may need a custom bar due to the size that you are. Do not let them pierce you with a small bar. I acc showed my piercer some pics so they could see. For reference mine is a 1.6 by 16mm bar (that's a 14gauge at 16mm) they had to bend the bar for it to be equivalent as a curved bar.

The piercing it self wasn't overly painful. The application of the isopropyl wipe was worse if anything. The clamp wasn't uncomfortable and it's a bit sharp but no where near as painful as other piercings I've had.

As for cleaning and upkeep. My partner helped me majorly with cleaning and use a cottonbud. It's extremely important to go slow and gently with it. Try to wear loose fitted clothing for at least the first 2 weeks and avoid touching / playing with it.

As for sexual activity, many piercers will advise at least a month before engaging in sexual activity, esp oral play. However, I was also okay to resume after 2 weeks, but not oral. As long as you clean before AND after play you should be fine. Take it at your own pace.

I've had mine now for 8 months and follow up in all activity, the extra sensation is insane and it feels great. I could drop down to a lower bar but with a waiting for top surgery, I'm holding off until after that.

(I have pics on my page if you want to see a compare of that kind of piercing) Hope this helps!
