Online guy

So I’ve been talking to this guy for about 3 weeks (only texting we live in different continents 😂) . He texts me like once every few days and sometimes i feel like hes only texting me for nudes. When i say that i dont feel like sending them he says stuff like “please baby” or “please im begging” but then he changes and says its ok if i dont want to but it almost feels like guilt tripping. Sometimes when i say no he says things like “why do you regret all this if thats how you feel then whatever” and sometimes i give in i know its weak 😫. Is this toxic??
