Confused about my sexuality

I have a feeling I'm the youngest on this form I'm 20 turning 21

And in general I'm quite confused I have a feeling partially it's due to a lack of experience

Everytime I find someone I'm interested in same sex usually I am very excited to meet them and do stuff when the meet actually happens I find it actually difficult to bite the bullet and Go through with all the stuff we talked about

Especially when it comes to anything Abdl or diaper related maybe it's just me being inexperienced and it comes with time ? But at the same time it makes me doubt my sexuality as if I'm bi I should be able to jump right into that stuff No?

As well as when it comes to self pleasure afterwards I sorta loose interest for the same sex and it comes back after a little while

If anyone has any experience with this id appreciate it
