Questions on flirting and the "mask"

Hello all. I have been doing nofap since quarantine. I used to watch porn all the time, but now I go on 6-8 day streaks and then end up relapsing.

I have made some great progress with women just from noticing my problems and improving myself. I have been really trying to push myself socially to interact with lots of people and put myself out there. One thing I have learned about is the "mask" I put on in front of other people. You guys probably know what this is. Its when you are not being yourself around others. An example of this would be if someone says something to you and you think a certain thing, but your mind views that thing as "bad" so you say something else. You aren't saying what your mind believes making you less able to connect with people.

The reason I bring this up is because as I have stopped doing this I realize that when it comes to women, my mind is very sexual. Its hard for me to explain this without sounding like a major objectifier of women, so just try to understand that I do actually value personality and I do like to get to know girls. Its the main thing. However I find that when I am talking to a hot girl, my mind is really thinking "holy fuck I wanna smash she's so cute blah blah blah". And it begins to get really hard for me to speak because I am constantly thinking about that in my brain, and my brain wants me to say it.

My question is how do I stop this? I don't think its a bad thing to think about sex, but I would like to be able to talk easier with girls.
