<human>: This guy (26 M) is my future, I know it (no matter how naive that sounds) and he says I am his too, but I just feel like I met him too early in my life. He's my first everything (late bloomer here) and I feel like I'm missing out on dating all sorts of people and trying other experiences. He's the same way too, he's only ever done anything with me but has no desire to try other people.

I see other guys and I get attracted and can't help but wonder what's sex with him like?
This might also be part that sex with him is far from perfect, but we're constantly working on it.

I can't exactly tell him to wait for me while I try new things. That's just plain selfish, I know.

Do I just banish this nagging feeling to the back of my head?

Summarize the given text in a few sentences.
<bot>: I've found the one I want to spend the rest of my life with, but I want to try new things and people I can't just ask him to wait can I? What do I do?
