Sharing room with close female friend for a week. Should I try something like conversation?

So I am sharing room with my female friends for a week in bay area she likes me and even said she wanted to marry someone like me (she could probably say yes If I ask ). But I want to get laid for now and don't want to get married or get a gf for now. So should I try something initiate conversation or something related to sex? Or just skip it and enjoy her company and trip to her place ? (Easiest way is to do fake promise of marriage but I am not a shitty person)
