Dilemma: what is this odd way of masturbating?!

Moody

Okay, so this will sound really strange but I masturbate without touching myself. I don’t use my hands, I don’t syntribate (rub my thighs together) and I don’t grind on anything. So what I do is I sit somewhere and start kicking my legs back and forth and tightening my lower abdomen muscles on reflex. It gets tiring and is like exercise. I rub and thrust my hips too but I do not feel anything at all in my vulva/vagina/clit except irritation and itchiness from rubbing. I don’t even feel any pleasure until the very end where the orgasm type of thing happens. I don’t even know if it is an orgasm but it feels like a good release and it feels good in my lower stomach I don’t know how to describe it? It’s like when you have to pee really bad and then you do and you feel relief it’s like that but more intense. Anyway, I don’t even make contact with my clit or vagina. I don’t even feel pleasure in my erogenous zones, I just feel it deep inside me like a release and in my stomach like I said. It’s very strange and I cannot find any info on it. The closest thing I found is coregasm? Does anyone know what I’m talking about? The only way I even know this is remotely sexual is because I only feel an extreme urge to do it when I have an erotic dream or see something that turns me on and after I do it I no longer feel aroused, I feel relief and satisfied. It is the only thing that satisfies me. If i feel horny and I masturbate the typical ways then I get no relief. How can I masturbate and orgasm the regular ways? I ask this because I don’t feel pleasure in my genitals it’s like I just skip that step and go straight to orgasm and it feels like I’m missing out on something big which I am since I’m literally not feeling pleasure externally. I don’t even moan or make any noise. It’s like if anyone had sex or masturbated and their genitals were numb and they felt nothing but they still orgasmed and felt good. It would feel horrible wouldn’t it? Please help.
