(Please excuse the title if it offends anyone. It's just meant to be fun.)
Let me explain.
When I was a teenager it was all kissing, fingering (usually v. bad) and giving blow jobs. The first and third I enjoyed. Once I had given a few blow jobs, I couldn't see a reason not to give a blow job to any new boyfriend, so that is what I did.
Later I started having sex and that was good too. After a few years, if I was kissing a new man and fancied him, I couldn't see any reason not to have sex with him straight away especially if we were in a relationship but not exclusively. So that is what I did.
Later on I had a boyfriend who said he didn't want a blow job unless I swallowed. So I decided to give it a go and now that is what I always do (it's better than I feared). So whenever I give a blow job, I always swallow, unless he really wants to cum on my body for some reason.
Later on, I had anal sex with a new man and, after a number of not-much-fun-attempts I got really good at it. Now I have done this a lot I can't really see a reason not to have anal sex straight away with any new man who wants to if I start a new relationship. So that is what I do.
And so on...
So if I start a new relationship, from day one I am happy to do any of the above and maybe a little more. If I think of what I would have said about such a woman when I was 20, I think I would have called her a slut. I imagine if I dated a young man, he might be quite shocked too.
Do we all just get sluttier as we get older? Or do some women reset when they start every relationship and start again from the kissing stage?
I should add that I have no complaints about anything I have done. I am very comfortable with saying no. I had one boyfriend who really wanted me to wax (intimately). I tried it once and hated it and will never do that again.
