Is it possible to be genuinely in love with someone but get excited if you talk to a new crush In a friendly manner?

Yes, there is always excitement in new things. The unknown is exciting. Love is predictable, because real love is stable and reliable. So it's not always exciting but it's life affirming.

I think it's normal to be attracted to other people.

It's how you conduct yourself that matters.

Hmmm

That would be ok

Yes
