Is this a red flag?

I am a 28 M. Ive been talking to a girl for the last 5 days and we have kind of had a sexual conversation. She shared her desires and asked about mine. We softly had a very brief sex chat.

But it seems like she likes talking sex a little too much (trust me if I say so, it is indeed a bit too much)

She brings in sexual stuff out of random and holds the conversation better if its about sex or foreplay but small talks about other stuff. Is this a red flag?
