Why do you act as if you're ashamed of being gay? It's perfectly normal. It's the way you are. There's no right or wrong gender to love. You're a perfectly normal and perfectly healthy 18 year old boy for being sexually and romantically attracted to other males. Don't let that make you ashamed. The sooner you accept yourself, the sooner you can liberate yourself and be free.
You are who you are, no other outcome could have happened with your sexuality.
