Tadalista 60 works by promoting increased blood flow to the penis, but this is only effective when there is sexual arousal or stimulation. After ejaculation, the body typically returns to its normal state, and the erection will subside. No, Tadalista 60 does not keep you hard after ejaculation unless there is further sexual stimulation. Tadalafil does not cause continuous erections without arousal, so after ejaculation, your erection will typically subside as the stimulation stops.
