We disagree a bit in the way we define things based upon personal viewpoint which means that I can’t say that you are wrong, just that I have another way of looking at it.
Sex: An act involving two people using their own and/or the other person’s genitalia for pleasure.
Sex with emotion (positive feelings for the other person): A sex act where you strive to give the other person pleasure.
Sex with emotion (negative feelings for the other person): A sex act where you wish to cause negative impact upon the other person (rape for example) and/or derive your own pleasure from the act and/or your desire for dominance.
Sex without emotion or any feeling for the other person: Perhaps with a prostitute where you could care less about how they feel about it or what they get from the act itself, it’s just all you.
Love: A positive emotion with regard to another person that may or may not involve sex. There are both women and men in my life who are not kin that I have love for, but it is not a sexual relationship.
Hate: A negative emotion with regard to another person. You could have sex with them but it would be the negative example that I gave above.
Like (possibly a friend): A positive feeling toward someone that has not developed into love (that takes time). You could have sex with them with the same positive attitude (mutual pleasure) just for fun. Sex is fun. People sometimes fall out of love when they don’t actually like each other. You can love someone that you don’t like.
After I had been married a few years my wife confided that when I asked her to marry me I was not the only man in her life (I knew that). She said that she loved him and she liked me a lot. She knew that based upon her genuine like for me that love would develop when we were together. Remarkably wise of her at her age. She understood the relationship between like and love. In April we will have been married for fifty years. Still in love, still friends.
None of that is to tell you what you should think with regard to that, it is just the basis for what I wrote.
