Background:

Met girl a few days ago at a party, made out and got blowjob.

Texted her hey, I had a great time, thanks. First mistake, shouldn't have said thanks. As others gave pointed out, thanks makes it sound transactional.

She responded with the above line that she was drunk.

I replied by saying we aren't ourselves when drunk, etc.

Edit: She texted again saying she was drunk, she's not that type of girl...

In the future, what would be a good way to build comfort / get that plate spinning? She obviously doesn't want me thinking of her as a slut, but I'm not sure how to respond to this in a funny way to defuse that tension.

She definitely cares about my opinion of her, why else would there be a second text?
