My Ideal Life in Another World Vol. 2

Our protagonist used to be a 40 year old male virgin until he masturbated too much and dies from a technobreak. He finds himself reincarnated in another world where men can only go into heat and procreate once per year yet he has a special ability to go into heat whenever he pleases. While in a library he discovers that this special ability is known as the "Monarch's Gift" which makes seminal fluid of men 100 times stronger than normal. This causes women to go into heat just by the smell or taste of it. With this knowledge in tow, what else will our protagonist discover?
