Is it normal i like my boyfriend to pull on my pussy lips

I act as if I'm shy of my lips because they do hang out a little. But I always want him down there and looking at them. I love when he licks them and pulls on them!!
We are very out in our relationship we talk about everything. He loves them to hang out. Here's the thing...
When he's down there I always picture him with another girl or him doing that to another girl. I always talk about other girls in porno like "oh baby I would love to see you lick that tight pussy" and he says "yeah I would do more then lick it, I'd fuck her in front you of" ohhhhh it turns me on!
I also don't like to call him in the day time because I like to think of him maybe cheating while I play with myself in bed. When he gets home we take shower then get right to sex! Is this normal?!
