He's talking to me a lot more then usual and it's about mostly anything. He never mentions liking anyone else. He flirts with me from time to time. I've known him for a while and have liked him for about 2 years. He'll find excuses to snapchat me. The other week flirty sent me a picture of his crotch area asking me if I like what I see. Nothing nude. He's snap chat me in his underwear before. He tells me personal things at times and he always teases me.
