I can’t tell you how to know if you are gay. It’s something you need to figure out for yourself.
Sexuality is fluid and it takes time to get to know who we are. I thought I was bisexual for a long time before I came out. I have met guys who have been with guys and then decided they like girls. I have older friends who have children and families from marriages.
If you are having feelings for the same sex then do not be afraid to explore those feelings. It is natural to explore who we are. You should not be afraid of that.
How can you tell if you are Gay? Well if you are sexually attracted to other guys then that is a pretty strong indicator i guess.
Gay is a label we use because it is part of the Human condition that we need to feel that we belong. Don’t be so quick to let your sexuality define who you are. It’s only a very small part of you. Don’t be so quick to label yourself when there is so much fun to be had exploring (just do it safely).
Lastly always remember… you are beautiful the way you are regardless of whether you are Gay Bi or Straight. You are as deserving of love and happiness as any other person on this earth.
It gets better 🙂
