My first sexual experience

I dont really know what should I say about my first sexual experience. Should I write about my first masturbation? Should I consider mutual masturbation as the first sexual experience? I was thinking hard what should I consider as my first sexual experience.
As a cute boy who was born and raised in very conservative society.. I did have some experiences where I was so sexually excited but not really happened more than being touched. Should it be the first time I got a blow job? Let me know how people consider their first sexual experience.. Some of the experiences I can recall for example, being touched in the crowd which I think is valid to be called as sexual experience since I remember I was so excited. Right?
