masturbation station

I've been getting on with myself since elementary school, weird I know but I mean I guess I just found out my body sooner than others. When I masturbate I don't really know if I have an orgasm or not, because after, I'm still super turned on. I've had orgasms before from my ex when he went down on me, but what I feel when I masturbate is no where near as good as what I felt with him. I have never really found anything else that works for me though, I'm really hard to please.. and the only way I get off is from a good amount of pressure on my lady bits. i really don't know my body better than others I guess. ☹ anyone have any suggestions or go through something similar?
