I'm going to date multiple people
Is there a particular reason why you want to date more than one person?
Ultimately, having multiple sexual partners makes me feel more appreciated.
As long as no one thinks you're dating them exclusively, it's fine to date multiple people. However, I am concerned that you need a sexual partner to make you feel appreciated - you should work on developing your self confidence in the absence of any partner.
I think dating multiple people makes romance more interesting since you can use those experiences to have more fruitful conversations with your partners and you also have a better chance of meeting the right person.
So long as you're honest, it's perfectly fine to date multiple people and your explanation as to why is sound. I just hope you allow yourself to have confidence even if you aren't dating anyone.
