do I ask?

me and this guy have been “talking” we met on new year’s <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> and we got each others snapchats and one thing led to another and we sent nudes. i’m just gonna be honest here. (I was responsible, no screenshotting, no faces etc) so we have been talking for a week or so now and he’s super cute and has been sweet to me. i’m scared that all he wants is the pictures since that is what happened to me with the last boy I got involved with. i’m wondering if I should say something and set some boundaries and say something like “if you are only here for the pictures, you came to the wrong place. i’ve enjoyed our talks, but i’m looking for something more than sending nudes all the time.” is that bad? idk I want to say it just to protect myself from getting hurt again but I feel like it makes me look too invested in something simple. let me know because I am at a loss.
