Should i text him?

So this guy & i have been texting for about a month. Had sex twice. The last time we had sex he literally only lasted like 3 minutes. I explained to him it was no big deal & next time he’ll have to double up (joking around) Well he hadn’t really texted me since. I’ve texted him 2 different times & his texts has been really dry. Like I’ll ask him something & he’ll answer the question & that’s it. This is our last text in the post. Should i text him to see if he even wants to talk anymore or just leave it alone? I don’t want it to seem like I’m bugging him but i would really like to know what’s up. I hope our lady incident isn’t what the problem is.
