New relationship sex issue

I've name changed...
This is possibly going to sound like a troll but I'm honestly not.

Ok, my problem is that I'm a few (6/7) weeks into a new relationship, after a long and mostly sexless marriage, and this new man seemed really nice, until we started having sex.

We used to text flirt a bit during the day. Now all he can text me about is going down on me, all he wants to talk about is how he is going to go down on me. When we are having sex, he just looks at my lady parts for ages like it's a fascinating new invention and I feel like if I could chop that part of my anatomy and leave it with him he wouldn't care or miss the rest of me at all. It's like an obsession and I feel like I'm not a person to him any more.

I don't know if this is normal, to get so interested in your new partner's genitals. To be honest I am finding it very creepy and I am thinking of ending things. I don't know if I'm overreacting though, I don't have a lot of relationship experience and I don't know if I am being unfair to him.
I don't have any healthy relationship experience really, I don't know how to judge if someone is nice.
Should I be... flattered? Is it creepy? :(

Oh and it isn't the first he has seen, he was married for 11 years!

Maybe it's something his wife wouldn't let him do and so he's got a particular fascination for it. The going down, not the staring, that's just a little off-putting.
Talk to him. Start a new relationship on an honest footing or else how can it continue in a healthy way?

(I'll just reply on the other one to stop it being confusing.)
