<human>: Condense the text into a few key points

I've been dating my fantastic girlfriend for the past six months now. She is my first in everything, while she has had 4 boyfriends before me and numerous FWBs and casual dates. 

Some time ago, I've begun asking about her relationship past and her time casually dating around or having flings, and she's always answered truthfully, at least to me, it seemed truthful. However, for the life of me, whenever she mentioned anything about her past, I didn't feel any jealousy or possessiveness, and as a matter of fact, I found myself more and more curious about certain aspects, like whether there was someone who had a certain move in bed, etc. 

I'm pretty sure I don't have a cuckold fetish - I do not wish to see her be in bed with someone else, and I intend to keep myself to the same standard. How is it that I am so unaffected when there are many posts here that talk about how he or she cannot get over his or her SO's past?
<bot>: I am never jealous or possessive when I hear about GF's sexual or relationship past, but instead I want to know more out of sheer curiosity. Why is that?
