There is this girl that I have met. We matched on tinder and have seen each other 3 times. First one was great but the past two have been so so, I don't think we connect as well as I thought we would and I think she may be losing interest (kind of worried I might be getting friend zoned cus I might not be acting strong and centered enough). However, we are two attractive people who find each other physically attractive. At this point, I'm more interested in sleeping with her rather than making her my gf. How should I go about this?
