So I have a physical relationship with this guy. I've never had this situation before. Kinda like a friends with benefits. I've noticed lately our sex is getting more and more intimate. He's calling me baby, telling me I'm all his, telling me he's mine, and asking me to be vulnerable. Sometimes we drink before just for fun and he gets very touchy and intimate with touching too. Is he getting feelings or is this just a normal part of a comfortable physical relationship? (We did make an agreement to only sleep with each other, too)
