My email acct is being bombarded w emails for ****

Can someone help me, almost daily my email acct (junk mail) receiving emails from people advertising 'ladies' or '****' etc. Some emails come disguised as being from someone you know that you open them and the are quite explicit about the services they offer others just state their intent on the subject line. I have tried using manage rules which worked in the beginning but who ever is sending them is getting a little more crafty and the manage rules is no longer able to stop them. This is really starting to stress me out as our email acct is used by the whole family - kids included and is only a matter of time before my kids are going to open one of these emails. I'm actually at the point now where I am going to shut down my email account because I am so feed up with getting these emails. Does anyone have any ideas on how to stop them?
