Advice?

So I’m not very experienced and I met a guy a year ago in person and we’ve been talking and sometimes we’ll start talking sexually but I always stop them because we’re friends and he moved to Asia for school and I’m in America and our future plans don’t seem to align to ever meet in person to form a relationship. Plus long distance wouldn’t be so brilliant bc we’re both young and wouldn’t want to hold either of us back. Do you think sexting would ruin our friendship? Like he respects me and I respect him back but I always have this distrust with men that if I begin sending nudes or sexting I’ll lose this stature of respect. Idk maybe I’m just overthinking it.. let me know what y’all think. Thanks 💕
