Been friends with/worked with a guy the last 4 years, we have gotten to know each other quite well and he has supported me quite a bit . About a month ago my convos with him have taken a sexual turn, discussing what we like and don't like RE positions fantasies etc. He accidentally saw a sexy pic I had sent my boyfriend at the time, this has escalated to him seeing a lot of the picss and vids I had sent him. There was a lot of sexual tension and we both talked about how exciting it was, this has turned to him asking what lingerie I am wearing, pics for him and a video call, I found out recently he had gotten back together with his wife, yet he still asks me for pics. Is he just using me for pics and pleasure. How would I know if he is just playing me?
