does physical attraction always comes first before emotional connection?

Yes you are true and it is fine to see friends who ahve lost due to physical attraction.Emotional atraction will be surely been turned towards to ahysical attraction.Hence both attraction is totally attracted towards the physical attraction.

I would say that there usually is some kind of physical
attraction first. That doesn't mean that the person is
gorgeous. It just means that the person is appealing to you,
that there is some kind of chemistry. Then there is the
emotional connection. Sometimes the emotional connection
starts like getting to know someone and being a friend.
You can have a friendship with a person for quite awhile
and never even think about any kind of chemistry and one day
something just happens and then....

emotional connection come when there is contact of the eyes, body etc.so physical attraction is all about what u see

I've always believed that physical attraction comes first before emotional connection. I mean, when we are outside say in a party, we usually approach those we find physically attractive. Whether we admit it or not. We always, if not most of the time, go after someone with good looks, good hygiene and good outfit. But I know it's not always the case. Like there are long time friends who weren't attracted to each other (when they were still friends) at first, not until they've gotten to know each other then they became a couple. I don't know, it's kind of hard to explain my point but that's about it.

Physical attraction almost always happens first - it's our animal nature.
But emotional attraction is what keeps relationships healthier, and partners together.

Not always. People often become just friends first and form the emotional connection long before they realize they're actually attracted physically to that person - and the physical attraction is often the result of the emotional connection.
