Humping the aneros

So I notice for me on my back or side . It takes Super long to get going with feelings to build . But if I get into doggy style with the toy in. I immediately start having interesting sensations . a rush comes my heart starts to race with body starting to tense up with pleasure . My lower half starts to hump uncontrollably. The wider I spread my legs the more intense it gets . Feels good then fades . I wait couple mines and do it over and over again .
Now I’m hot and bothered . But don’t want to touch my penis .

I sit on a chair while the toy is in . The motion starts to happen like on doggy style . Except I feel the toy hitting the spot that’s intense . I start to auto hump feels good . My penis gets partial hard with the tip feel sensitivity builds . I try to relax and not clench but it’s hard . I soon feel orgasm but it’s slow and tons of cum comes out . I still feel horny after but I never keep going . I’m tired . What do you think is happening ? Any tips .
