When you come out, it's normal and natural to want to surround yourself with people who have been through what you've been through, and who are like-minded. It's also normal and natural to want to get involved in your gay or bisexual community. Just remember that there is more to you than your sexual identity, and straight folks have to come to terms with theirs too. So, you may have more in common than you think, and those friendships are still just as valuable. While your new gay friends may be better at listening to your woes about dating, your old straight friends might know how you got that scar on your arm in the seventh grade, and may still love to go watch old movies with you on Sunday afternoons.
Friendships are about more than sexual identity.
They're about bonds. Don't break'em thoughtlessly.
