What makes sex "hot" is, of course, relative. What turns one person on can be a complete turn off for another, which is why there really aren't any "rules" for sex, other than it should always be with an adult, always be consensual and it should always be safe. Other than that, the sky is the limit. So whether it's with one person, multiple people, a woman, a man, in missionary or some obscure position that doesn't have a name yet; what makes sex super hot is entirely up to you. Having said that, there are so many reasons why sex is hotter when you forget to shave so, you know, maybe put down the razor and give some stubble a try.
I know, I know; this goes against the patriarchal ideal. Women are "supposed" to shave, so that they look more "feminine" and cater to the socially accepted yet ultimately sexist standard of beauty. It's also definitely worth noting, that if you do shave, you're not a bad feminist or a slave to misogyny. Being "girly" doesn't make you a bad feminist and it definitely doesn't mean you've yet to get "woke." We all like what we like, and for some of us, that's shaving on the regular. However, when you normally shave and either take a break or forget altogether (and then choose to be intimate with a consenting partner) you may just find that this tiny change can translate to massive gains in the bedroom. Suddenly, you feel like a different person, with a newfound sense of self, all because you left your razor alone.
I, for one, experienced this first hand when I was pregnant and shaving wasn't necessarily an option. I mean, you try reaching your ankles with a gigantic belly in the way. At first, I was pretty self-conscious about my now semi-hairy legs because I, for one, don't mind shaving. However, after a few romps in the sack with my willing partner, I realized that having sex when you've forgotten to shave can be the best sex you've ever had. Seriously, ladies. Trust.
