My partner and I have both gotten bored with our sex life. We’ve tried different positions, different lubes, even different ways of foreplay. At one point we even put up a porno to watch while we were doing it and that didn’t help.
We need help. We both feel like we need to do something different but we can’t think of anything. Please give me some advice!

Could it be possible that it is because you’ve lost romance in the relationship? Maybe you need to connect more mentally. Go on dates, and be romantic. Also, do something thrilling and adventurous, that might get you going.
I’m a big believer that great sex is a bi-product of a great relationship.. Are you both still finding one another interesting, do you go on adventures together, do you challenge one another. Find the relationship chemistry to do those things and I suspect you will be able to find ways to spice up your sex lives
You may need to spend a little time apart to get the spark back. Go do some hobbies and see some friends you both have not separate. It gives you something to talk about and not be joined at the hip.
Also try sex in a safe location where you won’t be seen outside.
