That is normal if that is how it happened and that is how you feel. Normal as in it is okay to have felt pleasure and to desire it today. The first time people have a sexual experience is usually very important. For girls if you have a sexual experience before the onset of puberty then you had a sexual experience before sex became a danger to you. So you had a sexual experience from the point of view of pure and absolute pleasure (according to what you told me) and that is something you can NEVER have again because you are older now and I assume can get your period. Freud said that the sexuality of women before their period is like that of a boys or mans. That explains much.
