So the guy I'm sexting is sorta like friends with benefits and he only wants to sext and I like him... a lot and I don't know what to do
Most Helpful Guy
That is not friends with benefits. Sorry, but that is not something that a friend would demand, and friends with benefits implies that you have to be friends. He is using you, and taking advantage of you, and because you like him and want something more out of this you are considering accepting his disrespect in the hopes that something develops.
If he is trying to say he will only show you attention if you send him a nude pic, he is most certainly not considering you 'relationship' material. And, given your age, what he is asking for can most likely be considered child P*rnography and is most likely illegal. In fact, just asking for it could be pushing the boundaries of the law.
What you do is say no. You have to have some respect for yourself. This guy is taking advantage of you, and is banking on the fact that you like him to push you into things you are not comfortable with. If he is pushing you into a picture before you are ready, he will push you into sex before you are ready. That is the behaviour of someone who cares nothing about you as a person, and is only using you to further their own needs.1
