Can I just point out your friend has probably been trying to hide it or tell you for most of their life as its not a personal choice, it's not something that you think "oh this might make me happy i will give it a try" It's so far from that its untrue. You know all your life you know that your gay/lesbian and dealing with it is kinda hard especially if there are peeps that think asking a question like "Is being gay bad" I think maybe listen to what you have just asked and wonder to yourself if your uncomfortable with the idea of someone being gay just imagine what it feels like for them to be gay and people still in this day and age ask that question. Sorry no offence meant but kinda personal for me that one. peace!
