Affiliate Marketing Secrets

So basically, I’m not affiliated with anyone I know in real life on Tumblr. I used to have two people I know from real life following me, but I blocked them and then changed my URL.
So, would it be fine for me to identify myself as a homosexual publicly on Tumblr? I’m in the closet in real life, and no one knows about my sexuality. However, since no one in real life will be able to see it, should I just identify myself as a homosexual on Tumblr?
