In the past, I would rarely experience this strange sensation where the orgasm lingers in my brain (this lingering orgasm feels uncomfortable). This has happened for about a year and a half now. However, it has become increasingly more common as of late. Other info: -It only happens at night -I m barely awake when it happens -When I m close to ejaculating, I start to think of extremely random things (ex: I ll think of firetrucks) involuntarily. Should I be concerned?
