Instant Climax: Conquering Reality With My Harem System

A dirty hobo old man was in an alley regretting his life choices and then decided to go for a piss at a nearby river when he was suddenly hit by a truck and reincarnated into another world, that however was just the beginning as the world he ended up in was one of the only men, where women didn't exist, so his fantasies of a harem of beauties were quickly dispelled for a world of femboys and burly men hitting on him. Managing to survive through trials and tribulations in this other world, he got the favor to make a deal with the Gods and got to use the ability of regression to go back in time and fix his mistakes at the cost of all his abilities and power, leaving only vague memories of the otherworld. The regression took him back all the way to the first day of his last year of high school, where everything started to change for him. Unfortunately, there was a mistake made… he looked like his hobo old self despite being 18 years old again. That caused him to be too weak, and as an orphan, he had nobody to fall on… so with that problem, he became a victim of bullying, but after all, he had been through, he refused to surrender without a fight, which led to him being dumped at the ocean to die… however he did not die… for some weird reason, he did not die, only losing consciousness then hearing a voice.
