Masturbation with hand or sex toy is fine, but the problem is with human penetration

Can someone please enlighten me with the science behind this phenomenon?

I dont think anyone wants to do this research or we would have some science on it. all i can say as that i am in the same boat. ever since i started trimix, i have not had a penetration orgasm since injection #4 and I’m almost 400 injections. trimix gives me great erections minus the desensitization that prevents me from orgasm. if i can have one, its with my hand or flashlight. all efforts to combat the effect have been primarily useless. it is a blessing and a curse. the wife gets worn out after so many orgasms but thinks shes not enough since she cant bring me to orgasm.
