Women and men truly are a separate species, each with our own quirks and personalities. While that could be chalked up to individual upbringings combined with societal norms, there also may be something biological at play.
However, sometimes it's easier to meet the person and see what they're like. Bisexuals fortunately have the privilege of interacting with both sexes on an intimate level and, thanks to the internet, reveal the knowledge they've discovered.
Reddit user, u/Rob-ThaBlob, wanted to know:
It's All In The Intensity And Power
I'm a man, and I like both, being with a woman is fun and passionate and smooth, being with a guy is hot and wild, and a lot more intense. Just my opinion
Top or bottom in M/M?
I would consider myself a bottom, Most of the men I have been with have been more aggressive which I like and naturally I respond to a more submissive nature, I find it very fun to not be in control and see what happens, when most of the men I've been with have been much stronger than I, I like to be in control as much as I like to be out of control. I love being with men either way
You Know The Set-Up Pretty Well
In my limited experience I've found that sex with other women is kind of easier. I've just had more practice with vaginas, I know what feels good for me and (so far) it translates easily to what feels good for other women. Sex with men isn't any less pleasurable, it just takes longer for me to figure out what feels good for them, especially since men tend to be less vocal in bed (which is a huge bummer, please don't be afraid to make noise to let your partner know they're doing something right).
Spending time figuring out what a new partner likes can be fun too, but with other women I always feel like I've got a head start (wink wink)
Gets The Job Done
Every woman I've slept with doesn't stop until I'm finished.
Can't say that for every man, lol.
Physicality Levels Vary
Other than the obvious... I would say that in sex women are gentle even when they are rough and men are rough even when they are gentle. That's not exactly right.... but its true though. And I don't just mean the act of penetration receiving vs giving. The only thing that doesn't line up with this is receiving oral sex from a man as man, which is amazingly gentle and good (or can be). But giving oral sex... way more physical thanon a woman. Even kissing is somehow more... physical, less gentle. A lot of the other answers are also true.
Act vs. Context
Everyone's different, but in general: Men are about the ACT, women are about the CONTEXT.
If a guy wants to screw you, or wants to do something specific they just want to do it. A freight train could be bearing down on them and they'd go "well, we've got time before it gets here, best not waste it".
What a girl wants to do is very, very much more determined by how she feels about you specifically, how sexy she finds the environment, what else is happening in her life, the fluidity of the communication, and the expectations (or lack thereof) for a relationship.
It's All In The Perception
for me it's a lot like getting dinner
sometimes I want a nice intimate night out with a diverse menu and great service (being with a woman)
and sometimes I'm drunk, it's 3am, and I just need to find a place that's still open (being with a guy)
Like Making Love To A Carpet
In my experience women tend to care more about how they're perceived than dudes do. They doll up, they get sexy, they shave their legs. Guys dont really do that. Most of the time it's like "oh I'm gonna get laid". Even when chicks are just DTF they're not just throwing on sweat pants.
Dudes tend to make awkward small talk more often. Probably because our minds focus on the end goal more than the act. Also, hair EVERYWHERE
Save the planet, shave.
Positioning It Right
For me, the biggest difference in the power exchange. With women, I'm way more toppish and with men, way more bottom-ish.
The sex itself is different but mostly just due to the parts.
However,...all of those reasons are why M/F sex is great... because of the sharing of feeling and sensation. And oral can be done as often as partners like. And anyone can and SHOULD learn to read their partners body language.
So, for me... lesbian sex means you take turns focusing on the other person almost exclusively, while hetero sex means you get to enjoy the sensations simultaneously or separately.
