When I go tanning at the beach I usually find a move secluded spot and wear a bathing suit that is not a thong but is on the skimpy side to give as much sun exposure as possible without being too indecent. The suit is very snug and at least has enough material to have the key areas just covered. Even though I go to a secluded area there are still some people around and I do get noticed. I always wear my bathing suit to the beach so all I need to do when I get there is to take my shirt and pants off and I am pretty well ready to tan. One time I got there and stripped down to my bathing suit. I began to put suntan lotion on when a guy nearby noticed I was having trouble putting it on my back and he offered to help. I said no at first so he insisted and I let him. A few people in the area watched us. He finished my back and offered to do my front. I am not gay but it did feel nice and when I turned around for him to do my front all I heard him was "WOW". I had an erection and it was very noticable to anyone looking my way. My bathing suit was extremely snug now because of my erection that it was becoming very uncomfortable and a little painful. I went to adjust myself which was my worst mistake. It popped out of my bathing suit and I couldn't get it back it. I tried for a while but couldn't bend it to put it back in without causing pain. I literally tried for about a minute before I finally realized I was standing with my erection on display for all the people nearby to see. I was in a little panic and just used my hands to cover myself. In doing so, my bathing suit dropped to my ankles exposing my ass. Still in a panic I quickly decided to just lay face up so my ass wouldn't be exposed and wait for my erection to go away. In laying down quickly my suit had come off so I was litterally on my back naked with just my hands covering my erection. I then decided it would be better if I lay face down because my hands were not covering me that well so I rolled over. My ass was fully exposed and remained that way for a about 5 minutes before my erection went away and I could get my bathing suit back on. Everyone was still looking at me but I figured I might as well just do one big exposure and get my bathing suit back on. I stood up, walked a few feet to where my bathsuit was sitting and put it on with no concern of how exposed I was in front of everyone. They had seen most of me earlier and now they would get another look but this time it would be a full look because I made no effort to cover anything. I did get a lot of looks but ignored them and got back to suntanning. The guy who helped me earlier looked at me too but didn't say anything and did his own thing.
