We have had this conversation before. There are some people out there that can casually have sex and other people that need to be in a relationship.
For me personally, i need to be in an exclusive relationship with someone i trust to have sex. There needs to be a build up of attraction. Like i would not just meet a random guy at a bar and sleep with him because he is good looking. That would not be a turn on for me. But getting to know him, knowing that he he is really turned on by me would then turn me on. Its the anticipation in the beginning. If i thought he was sleeping with other women and pursuing other women it would turn me off and we would not evolve. It would be an insult to my pride. Maybe other women see this as competition i guess, but it depends on the woman.
I think once you sleep with this woman, she is gonna assume you are exclusive. She is being direct with you. If you dont see potential for exclusivity with her, dont pursue.
Based on how i would view it, she might see it as right now we are sleeping exclusively together. As we continue dating and getting more comfortable we will see if the relationship gets stronger or fizzles out in which case no more sleeping together. To me this makes sense. How can you really get to know someone if you are sleeping with other people at the same time?
