Nothing comes close to the feeling of feeling your hot cum shooting up your cock and and spurting out into an unprotected pussy. I figure its probably one of the most natural fetishs out there - as its just instinct. It is unfortunate that it is suppressed at a young age. We are taught that pregnancy is the worst possible outcome of sex at a young age.
It's all perspective, but regardless of income and age I notice the people who view it as a curse they got knocked up tend to be miserable and struggle, while those who view it as a magical gift always seem to make it work.
Be responsible when breeding, but also appreciate the sexiness and magic of it.
