should i text him?

so i been talking to a guy for a month and we had intercourse and now he is acting all dry with me like barely talking..this happened monday and yesterday we barely talked i havent heard from him since yesterday like around 4pm..i want to think he is upset because i left right after sex and he wanted to chill but i panicked because somehow the condom slipped and some of his sperm got on me..i just wanted to go home and clean myself up..should i txt him and talk about that night or wait till he txt me? any advice? thanks
