My Ideal Life in Another World

Our protagonist is a 40 year old male virgin. Normally, he masturbates up to 10 times while looking at photos from the idol meet and greet events he goes to but upon the 12th time he dies of a technobreak and finds himself reincarnated in another world. In this new world, the gender ratio skews heavily towards females to the point that they make up most of the workforce. Not to mention everyone has animal ears! Another interesting fact is that males only go into heat once a year but Norun, as our protagonist is known as, carries a gift that allows him to go into heat at will. With this discovery, what adventures (and pleasures) will Norun experience in this new world? (Source: Denpasoft)
