'AIBU' is possibly not the right question! But in light of your observation about men bragging in the same way - no, you're not being 'unreasonable' IMO.
Our generation were brought up differently - quite differently - and as the world evolves, times change, and women have become more emancipated, it is inevitable that we are liberated from the constraints imposed on us - mainly by men.
I'm not going to judge these MNetters - with the usual proviso that if it's consensual, well - it's none of my business basically.
What I don't understand or condone is the need to brag about the number of conquests! Let's be honest, there will always be willing 'takers' if sex is on offer - so it's not really an achievement is it! I mean, how difficult is it to tot-up the number of encounters, I would think 90% of women could manage a big score if they had the time and inclination!
When men do this (I assume they still do brag) we usually dismiss them as misogynists - or men who need to grow-up a bit. So why do women feel the need to boast about the number of partners / one-night stands? To me, it just isn't a very adult way to behave.
The sad fact is that some men will still judge women on the basis of the numbers of partners they've had - and so will other women. Look at the way the media takes sly digs at women like Katie Price and various other female models / celebrities... and then read the judgmental comments from both men and women, condemning them (sometimes in quite vulgar terminology) for the number of partners they've 'got through'.
I think both men and women should stop bragging about their conquest score, it's 'naff' and immature. Freedom and liberation is something to enjoy - it's not a competition!
