Well, in general, post - orgasm for men can be a complex mix of physical and mental states. Physically, the penis becomes flaccid and the whole body's arousal level drops significantly. Some men might feel a bit sleepy due to the hormonal changes. Mentally, they may start thinking about other things, like getting some water or just lying there enjoying the moment of peace. It's a very personal experience though, and can vary from person to person.
In general health terms, after orgasm, men often notice a change in heart rate. Initially, during sexual arousal, the heart rate may be elevated, but post - orgasm it starts to return to normal. Also, breathing which was likely faster during arousal, slows down. There might be a slight perspiration due to the physical exertion during sexual activity which is normal and helps regulate body temperature.
In a scientific context, post - orgasm in men can be related to the body's return to a normal state. After orgasm, the male body undergoes a decrease in sexual arousal which is associated with changes in the nervous system. Some studies suggest that the brain's reward system is also involved. It releases chemicals like dopamine during sexual activity and then has a different pattern of activity post - orgasm.
