I'M A VERGIN GUY AND MY AGE IS 20.LAST 2-3MONTHS I LITTLE BIT CONFUSED ABOUT MY SEXUALITY.WHAT AM I ? STRAIGHT,BI-SEXUAL,GAY But,last 2days I really very stressed and fully confused about my sexuality and yesterday little bit fever started. Before Few years I watched a gay porn for just known the what type of sex it is And I don't liked it. And 2-3months before I suddenly in my mind came to watch gay porn. Then after I very weird fill about it. I also2-3times tried to finger myself.but, only that time when I did hand job. I don't know this what type of happened with me. Sometimes,when I hand job did that time I thought about gay men.but when completed I think it it's very weird about it. This type of happened in last 2-3months in interval means a some day gap after 1-2days this things come. Yesterday I watched both porn video gay and straight but no one turn me on.So,after really confused what it is things happened with me.And I don't like gay and bi people.it is negative on my mind.
