5 second sex..

My SO have been together for 2 years. And he always finishes within 5 mins. I have a higher sex drive now that I'm pregnant, and after we sex hes all spread on the bed, breathing heavy..and im like in my head "that's it???"

We do have foreplay..its ok..but im talking about sex

I tried to teach him stop when he feels like cumming...but it never works ); I'm super annoyed...

I can always finish by my vibrator ..but I feel like I'm missing a connection with him.

What do I do ? What can I do
