Expertly, even though there's a little bit of science behind moaning, all you need is some sense to predict faking an orgasm. Sadly, most active sex partners can't be able to notice that sensual fact because most passive sex partners act smartly in bed, especially to balance out the erotic moods!
In the heteronormative scenario, a few studies strictly reveal the fact that only female humans can moan in every sensual act, be it foreplay or genital intercourse. But typically speaking, a person who plays the role of receiving or getting penetrated can moan. In the queer community, say it, gays, the gay men who are bottoms also moan and fake too.
Moaning is a default sexual behavior that comes out of sensual emotions of pleasureful pain and painful pleasure. The level of moaning is always subtle, deep, and utterly engaging. It elevates the erotic vibe around and gives a hormonal boost to either of the sex partners. And indeed, moaning also helps a couple to climax mutually, regardless of gender and orientation. Interestingly, the receiver gets to experience the feel of moaning better than the giver. So mostly the people who play passive roles in bed are more likely to experience the part of moaning in sex and of course, they are also the ones who are more likely to fake an orgasm too!
As mentioned earlier, the feeling of moaning makes a couple embrace the sensual atmosphere with the senses of touch, hear, and sound. It drives the giver or an active partner or a gay top to go intense and wilder gradually and make the receiver or passive partner or a gay bottom feel every thrust, experience the pain and pleasure, encounter the sensuality through contracting and relaxing. Yes, a person can moan during blow jobs, rim jobs, and genital intercourse because all these sensual acts involve all five senses. So, experiencing an orgasm becomes easy.
Vaginal sex and anal sex include deeper penetrations and the constraint of pain. Moaning eases the pain out by relaxing the anal muscles and vaginal nerve ends. When a person moans, he/she/they breathe faster with the release of voice that diverts from the pleasureful pain one receives through one's genitals. Similarly, it can also be seen in men but at more moderate levels. They likewise feel the melange of pain and pleasure during thrusting their manhood or receiving a blow job but it's more of a subtle moaning and inclined towards pleasure. In contrast, receivers feel the intense level of moaning as it inclined towards pain.
