Ive tanned hundreds of times over the years, about 8 years, without covering it. I just have a dark penis regularly and it gets really dark when I tan. I dont have any problems though yet from doing it. Most tanning places are getting better bulbs and making tanning a better safer experience then it used to be so I say dont worry about it unless you dont want it to get dark.
(we owned tanning beds when I was growing up if you wonder why my age would of been so young when I started tanning.)
