At the core of healthy sex resides consent, but sex between two (or more) consenting people is not all it takes to have the healthiest kind of sex. Yes, sex should be mind-blowing every single time you have it, but earth-shattering orgasms are not all that sex is about.
The healthiest kind of sex involves a lot more communication than just some grunts, gasps, and moans. Everyone involved in the sexual act should feel completely comfortable saying what they enjoy and don't enjoy.
That much is normally pretty easy, but the hard communication comes when something was done that hurts the other person. No one wants to hear that they accidentally hurt their sexual partner, so perhaps the one who was hurt just keeps their mouth shut. That's not healthy. The healthiest sex is between people that have no fear saying "ow" or "no" to any act.
Communication is not just sounds, though. Communication also comes from body language and facial expressions. Now, if you are sexually active, then you know that certain movements of the body are synonymous with a pat on the back. Certain facial expressions mean that, too.
However, there are some bodily movements that might be mistaken for a pat on the back when they really mean that the person is just trying to get through the sex. Here's a personal example.
When I orgasm, my body goes rigid and back arches. When something hurts or I'm fighting a really random panic attack, my body goes rigid, but my back doesn't arch. In an instant of a non-healthy sexual encounter, the second instant could be mistaken for the first. In a healthy encounter, the difference would be noticed and dealt with accordingly. In a more common instant, let's say you get a muscle or joint cramp. In the healthiest kind of sex, sex would pause and the muscle cramp would be dealt with before resuming your play time.
Healthy sex involves a lot of communication, but the healthiest kind of sex is void of mortifying embarrassment, which is not something other articles similar to this one tend to cover.
While Bustle's article on "What Kind of Sex is the Healthiest" does talk about being comfortable and being able to get past the possible hang-ups, it does not mention anything about embarrassment. Naturally, there will be things that happen during sex that you don't really want to have happen. However, they do.
Your guy is pounding into you at the exact right angle that makes you let out a giant fart. Now, that is not the sexiest thing that could ever happen in bed (or wherever you might be), but in the healthiest sexual relationships, this wouldn't be completely embarrassing. Yes, you might blush a little bit, but you would laugh and move on. Now let's say instead of letting a fart rip, you are trying a new position and it just isn't working how you thought it would.
Sure, those moments might get awkward while you are trying to adjust your bodies, but no one is mortified by the situation. The all-time healthiest sex might even include laughter while attempting something new. Embarrassment is part of all aspects of life, but healthy sex shouldn't leave you mortified about anything.
While these are technically only two things, these two things seep over into a lot of smaller aspects that make sex healthy. Sex should never leave you feeling like you need to say something. Sex should also never leave you feeling like you want to hide under the comforter for a couple hours.
If the sex you are having is leaving you feeling any emotion other than bliss (and maybe hunger), then the sex you are having is not healthy, and there is a need to communicate with your partner(s). Go out and have mind-blowing and healthy sex!
