Do you believe someone can love 1 person emotionally/sentimentally but has infinite casual partners for sex?

When I used to tell my friends this, they say this is not love but me I am persuaded it is. Those with whom I have sex, I have no feelings for them and it's just pure physical pleasure but the one I love is deeper and I can even go to extremes as committing suicide just for them.

Am I the only one like this?

No you just have not yet become emotionally mature. Counseling can help.

Love and Sex are different things.
You can love someone without having sex with them.
You can have sex with someone without loving them.

That being said, the way you've described your romantic relationships, not just in this thread, but in many before this one, does not sound like love to me.

I'm not attempting to be mean here, but just simply honest.

It sounds like you're attached to the idea of the fairytale love and so you become overly attached to any man who comes along and sparks your interest without taking the time to get to know him as he is. This means you don't fall in love with the man, instead you get attached to the idea of the man, and the idea of the relationship, as you choose to see it.
That's not love hun, and it's not healthy.

I certainly wouldn't presume to define your relationships for you. And I know nothing about your history. I feel that love, for you, is how you define it, not how others define it for you.

There are quite a few polyamorous people around. You aren't the only one. But they might define love differently from you.

I think most people go through their entire lives without ever encountering real love.
A lot of people say they're in love but it doesn't mean they are. Are those insane
people who say they love their partners so much they killed them for some insane
reason really in love?

Have to love yourself before someone can love you.

I believe in polyamorous relationships, as long you're safe and both parties are ok with it then why not?

However suicide for a partner sounds more like obsession and dependency than love
