could it be that you are bowing to the pressures of society to identify your sexual identity? it is ok to not know. it is ok to explore and be uncertain. you dont have to put a label on yourself. i see all kinds of posts on here from people feeling guilty for what they do sexually and i believe this is because they feel they are going against societal norms and i will tell you what i tell them. screw social norms. as long as what you are doing brings you pleasure and is not harming anyone, do what ever you want. explore as long as your want, take your time and soon enough you will discover who you are.
