Sex and Phones

I really enjoy having sex with my significant other and I want to say he does too but every time I’m on top (reverse cowgirl) when I look back he’s texting or playing on his phone. I see it as disrespectful but I’m just trying to make sure I’m not over thinking or overly sensitive.. this time it kind of made me a little upset I kind of just walked away and cried to myself. Thoughts? Opinions?
