It seems you are enquiring about NPT - nocturnal penile tumescence, i.e. wood while sleeping. It has been hypothesized that testosterone-related excitatory actions manifest as NPT. Hence, if you raise your testosterone levels minutely by activating yourself sexually, you could trigger more NPT. But no one knows for sure - these are assumptions but nothing is conclusive.
I notice that my penis erects several times during my sleep, but when I have sex on a consecutive basis, like twice in a row during a two day period, I would have more erections during the night. Whereas, when I stop all types of sex including masturbation for a week I have lesser erections during the night. is this common?
