Concerned? WHY? Would it matter? Would you love him any less? Truth is,.. if in fact he is truely gay, there is nothing you can do to change it! No vodoo, No excersism, No shock therapy etc... What also disturbs me about your question, is your steriotypical view on WHAT a gay person looks like, and sounds like. Your ignorance is so unbelieveable! What do BLUE EYES have to do with sexual orientation? Not all gay men are blue eyed, and thin with little muscles and narrow shoulders with high pitch voices. Not all are feminine either! I've met some gorgeous, Very Buff and very masculine men, with deep voices and various eye colors,.. that are gay. As for having a "Tenor" singing voice,.. Look it up! It's a real vocal term,.. A MALE voice between baritone and alto, ranging approx. from one octave below middle C to one octave above it. My Dad sang baritone in a church choir for years and there was always at least one Tenor. Look,... I have sons,.. and truth is,.. the only reason I wouId hope for them not to be gay,..is because of how ignorant society is towards them and I know it would be a harder life for them. People can be catty and cruel to anything different. However i have seen improvements in the last several years. But make no mistake,.. if any of my sons were gay, i'd love them and support them NO matter what their sexual orientation and they would come to me and tell me because they know that's how I feel. Being gay,.. IF he even is,.. DOES NOT make him less of a man! TRY to remember,... He's YOUR SON FIRST,.. above and beyond ANYTHING else!
