Pornography
Sadly, 90% of porn is bullshit; it’s not an information source for great sex. Porn is a mirage that creates and exploits addictions in the name of profit. If you need to watch porn while having sex in order to orgasm, then you’ve got a problem. However, if it is your thing, please try to remember it’s just an acting gig, a job in which actors are paid to recreate a male’s view of erotica, not a woman’s.
If you’re unsure what’s healthy and what’s not, porn is the wrong place to find the answer. While a small minority of women might actually enjoy things like aggressive fingering, anal, jackhammering, strangulation, or pretend to like it in order to win favour, believe me, the majority don’t. If you’re still in doubt you don’t have to take my word for it, just ask your mother, your wife, your girlfriend. Or Google.
In the end, great sex comes back to asking. Don’t presume the woman you’re having sex with is turned on by the same thing as you, discuss your fantasies with her first. Ask what she wants.
