Next step

I’ve been dating my girlfriend for almost 6 months, this is our first relationship for both of us so we are pretty new to things. Lately I’ve been really wanting to take things a step further like foreplay and dirty talk not full getting it on yet. I’ve tried to hint to her subtly but she isn’t getting it or doesn’t want to. I have no idea how to start a conversation with her about this without making her feel uncomfortable, I also don’t want to pressure her into anything I just want to progress I guess? I don’t know. Any advice?
