I'm not sure myself what the neutical star means up until not to long ago, but I do have one on my forearm and I'm definetly not a lesbian. I got the tattoo just because it was something I loved to draw constantly and decided to make it permanent on my body.
All stars: black, blue, nautical, etc. DO NOT MEAN THAT A PERSON IS GAY. If you wanted a "gay" tattoo... you would get a rainbow, an upside-down triangle, etc. Butterflies, roses, stars, or anything else does not stand for gay pride. Gay people already have a rainbow to represent them. They don't get to choose what else represents them. It's not fair to all the straight people who got a symbol of a black star (me) and was told later that it meant that I was gay. Stop making up stuff. Our tattoos represent something special to each of us.
