Totally possible.
First, let's define LOVE
Is it some excitement when you feel when you see a beautiful girl on the road?
Is it something that brings peace to your soul?
Is it something that keeps restrictions on you? Or is it something that liberates you?
Is it something that makes you like people for their virtues? Or is it something that makes you accept people for who they are, even if it means accepting their flaws?
Is it something that makes you lie? Or is it something that gives you the courage to face the truth?
What is this LOVE?
Many people would agree, LOVE is about giving what you have to the other person without expecting anything in return. If they give you something, fine, you will take it. If not, you don't bug them to give you something. It is LOVE in its pure form. It is possible to be in this kind of LOVE with many people. And you may never know about it. And it doesn't see any gender, race, age and stuff. You can be heterosexual and LOVE someone of your sex. He/She may be your friend or a family member.
But are we talking about that LOVE?
No, I don't think so. We are talking about LOVE with benefits (LOVE with impurities). We give what we have, we expect something in return. The degrees may vary but we expect something in return. Nothing wrong with that as long as you keep it with one person as that means you are not available to someone else. You are happy. But if that happens with many people, well, nothing wrong with that too, as long as you are not cheating and giving people false hopes.
It just means that you have so much need, it might be physical or it might be emotional. If it is physical, well, we call it LUST, if it is on an emotional level we call it LOVE. But the bottom line is both are needs. Nothing wrong with fulfilling your needs, as long as it doesn't hurt people, it is just fine.
And I don't know why many people think, emotional needs are better than physical needs. I don't understand why people see the physical need in a negative light. For me, the physical need is much better than emotional need. Just a few minutes of pleasure, we are done with it. Emotional need, on the other hand, eats time and energy. It makes people do stupid things with their lives. If you want to call it LOVE, fine, it is LOVE.
I belong to the second category, I LOVE someone and expects to be with them. My LOVE is true but it is not pure yet. To make it pure, I have to let go of expectations. It takes time to refine such LOVE, it takes some processing. If one can go through that process, at the end of the road, your LOVE will be purified. Then it will be possible for you to LOVE many people.
Having said that, you can't penetrate many girls and say I LOVE them all, you can't take many dicks inside and say I LOVE them all. If there is a need in you and you LOVE them to fulfil your need, please don't call it LOVE. It is LUST. And it is totally ok to LUST so many people. Just use the right branding, it will save you from so much pain and keep you away from causing pain to others in the name of LOVE.
