Extremely important. Without it you're just friends.

Depends entirely on the people in the relationship. Some are highly sexual, some are highly asexual. Some people are good with sex outside the relationship to allow for the differences.

It is, sadly, something we are taught not to talk about and it ends up breaking relationships due to incompatibility.

We'll, it puts the wet in...

In my opinion , that's your body telling you , if there's some problem with this particular relationship , that you have't recognized, yet . Wouldn't want sex without it .

Very. If my head can't get with him, he's not getting my head.

I believe it is one of the core attributes of a relationship. If the chemistry isn’t there then what you have is a friendship imho. I know I can’t fake that.

How much varies with the people, but I think for most of us it is at least fairly important right up front in a relationship but over time other factors increasingly compete with it and may (hopefully) surpass it. Factors like friendship and loyalty and respect. Chemistry alone has led many into miserable relationships where the person comes to realize they are stuck with an attractive but horrible partner.

It's Being in Love (Chemistry, hormones) vs. Loving Someone (friendship, loyalty, empathy, respect)

If people are merely seeking a close platonic pal - then maybe not so much . But for most that seek love and affection, it's kind of up there on the list, like ...uh... breathing .

For me, rather important, otherwise it's a friendship.

Very much for me,
it has made a couple of relationships amazing, lack of it is why others haven't developed.
Not talking physical attractiveness, but the engagement of the 2 people.

sigh I am not a sexual person

I think it's important if we're talking about sexual compatibility (similar levels of sexual desire, interest in the same realm of experimentation, etc.). If you mean intense passion, I think that's far more subjective and not everyone needs or wants that.

Is it not just an extension of the relationship chemistry, assuming the relationship developes a physical aspect? I can have, albeit many moons ago, great sex with someone I don't love but sex with someone you love is on a totally different level.

Who wants sex anyway?

Well, without the sex, it's like friends with benifits... without the benifits... and eventually the friends.

It’s paramount!

REALLY?

Very important

Very important, if it's a romantic relationship.

I suppose it's a matter of perspective. Once upon a time I absolutely had to be physically attracted to someone for it to be sucessful. However, as I've gotten older I can't abide by sleeping with someone I can't carry on a conversation with. Having said that, bad sex is just bad sex and can lead to other intrinsic problems. Just my opinion.

I think sexual chemistry is 50% of the relationship. If I can see myself in an intimate scenario with this person, then there is definitely a sexual attraction.

Pretty important if the relationship is supposed to be an intimate, living, "romantic" one.

Dated a guy, really nice guy, smart, hard working, great conversationalist. Wasn't sure how I felt romantically, but things were progressing & I was feeling warmer towards him....then he kissed me. Nothing wrong with his technique but was the flattest, most unexciting thing to ever happen to me. Was the literal kiss of death to that relationship. Zero chemistry.

It's got to be there in some significant level. Personally, I'm a big fan of it.

I find it extremely important. I was in a relationship once and it was of no importance to her which made my life very edgy. Its also something that makes dating frustrating. If there isn't sex it's easier to got your separate ways but until you find out whether your both on the same page it's hard to commit.

Really important to me. I generally want to desire my partner sexually and want for them to desire me too. Sex is important to me. I have very diverse, inclusive tastes in terms of what I find desireable and sexy--not all of it strictly physical either. My big thing is finding someone who's sex drive is at least moderately high. I would have a difficult time being with someone who consistently/naturally had little to no sex drive because I have a very high sex drive. Not saying it could never work or that I couldn't still love someone with a low sex drive, but it could put a strain on the relationship if I'm walking around with huge boner most of the time, desiring my partner, and they're like "meh". I wouldn't take it personally if it's just how they naturally are, but it would be difficult especially if we're exclusive (which is the relationship style I am used to).
