I'm 27/m and she (26/f) thinks I have too many partners

Ok Reddit, I need some advice.

I am 27 and I just moved to Michigan last month. I graduated college in December and got a great job right out of college as an engineer. As soon as I got here I checked out the dating scene as there was not much else to do. I met this great girl. I'll change names to protect identities so let's call her Ashley.

Ashley is great. She's an artist. She's really kind and sweet. She's unlike any girl I've ever met. And gorgeous. Like, I feel like the luckiest guy when we spend time together. We only see each other about once a week because of my work schedule and her work and hobbies. Going that long without seeing her is actually quite frustrating. That's how much I enjoy this girl's company.

It wasn't long seeing her that it became clear that I'm much more experienced when it comes to sex than her. No big deal. She has made it very clear that she does not want to jump into a sexual relationship without dating for a bit. Again, I'm ok with waiting. I'm not having sex now, I'm enjoying her company, so there's no loss as far as I see it but an important addition to my life is spending time with her. Although, I hope the possibility for a deeper relationship, including sex, is somewhere in the future for us.

So today we are chatting via text and she asks me what my "number" is. You know, how many different women I've had sex with. My number is approximately 10. I don't keep a running tally at the forefront of my memory but last I thought about it was like 10-12. Mind you, I'm 27 and I lost my virginity at like 16 so this is about one new "conquest" a year since I became sexually mature. Now, these 10-12 women are a mixture of relationships that were in progress but went awry, relationships I wanted to happen but it was just sex for her, and one night stands. Actually, very few were intended to be one night stands on my part, but I digress.

So I tell Ashley my number and she's freaking out now. She wants time to think and "absorb" this new information. I think she's being petty and judgmental. I know my number is 10(ish) and her's is only 2 but I would hardly call myself a man-whore. And, in addition, I always used a condom with these women and get routine STD and STI screenings. I feel like I am getting punished and unfairly judged for telling the truth now. If this is the backlash I get for my past how can I ever tell her the more major mistakes I've made in my life? I just got out of college. I feel like the man I was prior to last month is not the man I'll be after this major life event (graduating) and moving to another state.

So, should I stick up for myself and tell her I think she's being petty and that there's nothing wrong with being a 27 year old with 10 past partners, or am I crazy and am in the wrong? I think it would also be interesting if you would share your stats and your number with your opinions. I'm just curious to know how many sexual partners people have had.

Thanks,
