I had the same experience as groan_man. My piercing was totally painless, maybe because I had always enjoyed playing with sounds, those steel rods you insert into your urethra. My piercer recommended going with the largest reasonable gauge for faster healing time. I started with a 6 ga and healed in 3 weeks. Two months later I increased to 4 ga then another two months I went to 2 ga, which looks and feels great.
At first pissing was easy. I would tug forward a little on the ring and the flow would go forward. Later, as the hole has stretched, the piss tends to go down as well as forward so I do what groan suggested. As much as I love pissing at a urinal or trough I now tend to sit most of the time. For me it is no problem.
I love the weight and look of the ring. I do remove it if I want a vigorous hand job, otherwise the weight of the hardware can bruise the tip of my cock.
I wanted this for over 25 years before I did it and have no regrets. My nips are next but they take a couple months to heal, and maybe a guiche. I can’t answer about the apadravya since I never wanted that piercing, or the g-spot since I’m gay.
I say go ahead and give it a try. Make sure you go to a reputable piercing studio with immaculate cleanliness and sterility. Be relaxed. Tell the piercer everything that concerns you, especially your concern about your frenulum. The piercing hole always go to one side or another of the frenulum.
I started PE after the piercing but, when I stepped up to 2 ga (about 1/4” diameter piercing), it took another 2 weeks to heal. I would suggest no PE until at least 4 weeks after your piercing. When I jelq with the ring in place everything swells and the ring becomes very tight. If I remove the ring before a session the swelling closes the piercing hole. I have to wait a while before re-inserting the ring. However, you should only remove piercing hardware after you are really totally healed. Otherwise you might have to return to the piercer to stretch your piercing again.
Lastly, if you find you don’t like having a PA you can remove it and the hole will eventually close. Go for it.
