Few things beat having passionate sex with a young (+18) ravishing female, especially if they're European, Korean, or Japanese. Unfortunately most women aren't beautiful, don't keep themselves slim, aren't young, and those who are either are gold diggers who'll divorce you or aren't interested in a relationship or sex.
I have met plenty of women who are gorgeous and I was interested in sexually and even romantically but asking for sex is inappropriate and being turned down is both anxiety producing and agonizing.
Both masturbation and sex carry risks:
Sex could lead to pregnancy could lead to paying for child support and even never seeing your child again. Being in a long term serious relationship with a person of the opposite could lead to common law marriage by the state due to cohabitation could lead to paying alimony to your spouse after you break up for the remainder of your life even if you never married. Nowadays simply interacting with a woman (though not a man) could lead to legal issues because women are hypersensitive and seem to carry a hatred of most men but don't know how to stand up for themselves and use the state and lawyers as a white knight. Women don't even seem interested until they're over thirty and by than we aren't pursuing their wrinkly roastie puss.
Masturbation could lead to porn addiction. Masturbation could lead to the development of more unique fetishes and longer to climax as you seek your unique and hard to find fetish. Some sexual fetishes are shameful, disgusting, and embarrassing to its holder, or are rare as few people have those fetish, I am one of those people. Masturbating too much could lead to callus forming where you stroke most and lead to longer time to climax and this is a death sentence for women because callus on the clitoris usually means little to no sexual relief. Masturbation can be a waste of time.
If the West wasn't so hostile to men yeah I would pursue the girl of my dreams to cohabitate, get pregnant, and have lots of fetish sex with. Funner than a body pillow, sex doll, and artificial vagina.
