I am wondering if I'm demisexual or asexual. i am 21, almost 22 and have never been in a relationship, i have never kissed anyone, i have never had sex and when I think about it i feel like I am scared of intimacy, i don't feel drawn to sex , don't really think like i want to have sex,, even the thought of kissing someone and being physically close to sb, not neceserarilly in a sexual way, is kinda sary and makes me a bit uncomfortable. and i don't know is it is demisexuality, asexuality+

I will answer this in the second part of your message
