Help we don’t have sex

Me and my bf haven’t had sex in three weeks. We had an argument that really ruined our sexlife but we have talked it trough three times and don’t want to have that convo again...

but the sex drive is dead.

Any tips how to get it going again? We’re just like best friends that snuggles. ☹️

Btw is there anyway of replying you guys and still being anonymous?
