I think ruined orgasms are quite good for that, as you can keep going directly afterwards. You’ll still be horny and don’t have that “post nut clarity”. With time you’ll learn to do it anyways if you do it more. I recommend not just eating it pure the first times, as the taste might put you off

Also, you should know that cum goes bad really fast, like in less than 5 minutes. It gets really disgusting, so you should eat it fast. Some people recommend freezing it, but as a person with experience on that, if you don’t immediately freeze it (basically standing next to the freezer while you cum) you just freeze bad cum that might include bacteria. The thawing process also sucks because it keeps getting bad during it. I don’t recommend freezing, fresh cum is always the best
