Greetings,
I view a lot of letters that represent words. Some employ this system of communication when they "Text Message."
As regards the question. Be proud of your boner. If you are at a beach you can lay on your stomach. Or, you can remember the mantra that "It pays to advertise."
Now regarding being proper in a work like setting or even a social setting where a boner would not be considered proper - You can wear a jock.
Also, please be aware that a boner can also be considered Normal. There are several drug companies that produce pills to allow boners and they must be making a lot of money because they do a lot of prime time ads on TV, which are not cheap.
Some day, as you mature, or even age, the propensity for a "Boner all the Time," will resolve itself.
Also, if you are still plagued with Boners All The Time, you may try wanking (a.k.a. jacking off) more frequently.
Just a thought.
Enjoy life, as I close this message. I hope it helps.
