change the locks. it is your house, your rules. you are not being unreasonable. if he wants to get jiggy with a complete stranger he needs to clean his back seat.

Change the locks....Then re-emphasize your request that he discontinue bringing the strays home with him. I hope he takes it OK.

If you are the head of the house, kick him out. After talking about it with you, and continuing this, it'd be considered taking advantage of your hospitality. Suggest to him that he start going to their houses and give him a date that if he doesn't stop bringing girls home by then, he's out.

Tell him that it is in fact, your house and not his house and that he is a GUEST in it. Tell him that it is your home and not a knocking shop. Tell him that while you have no objection to the odd person spending the night here and there, you will not tolerate a succession of complete strangers being brought into your home, week in, week out. Period. Then, pause for breath and before he says a single word at all, finish off by telling him that if wishes to continue in the same vein, then he will need to find himself alternative accommodation within 4 weeks. Say that you are not trying to tell him how to run his life and what he does outside of your HOME is his concern. However, what happens under your own roof is down to you and as this is your house, you make the rules. In other words, if you don't like the rules of the house, then get a house of your own and then you can do as you wish. Be assertive about this. When you say your 'speech', do so standing up (it helps) and say it in a calm and controlled manner. Don't pass judgement or be emotional about it - instead be matter of fact - be firm and clear. Say it like you mean it in the same way you would scold a toddler. Remember, you are not asking, you are telling him. Stick to the facts and look serious - tone of voice is important - be stern. Once you've said it all, ask him if he understands, tell him it's not up for discussion, tell him he has until tomorrow to think about it and then you want an answer either way. Think 'angry parent' saying to you as a teenager (when you rolled in at 5am) 'don't treat this place like a hotel'. Good luck (not that luck will have any bearing on your success). Oh and he will go into a massive sulking session - ignore it.

How old is he, and is he paying rent? If he is over 18, and paying his way in the house, it is rude of him to do this, but not illegal. If I were you, I would tell him to get his own place if it bothers you that much.

Ever think about kicking your brother out of the house and having coffee with the stray?

So he just dumps these womem at your house and goes home?

change the locks

He obviously is disrespecting Tell him if he comes there again, you will call the police. Change your locks, and call the police if he tries to break in.

He's OUT!!!!!!!!!!! That's all there is to it, if he can be rude enough to bring strangers into your "home" You have every right to kick his butt out! ASAP

He leaves then there IN THE MORNING? Is he using your home like a whorehouse? Don't wait. How expensive can it be to change the locks? How many doors do you have? You can get a lock set at WalMart for $9.95. If you lived close enough, I'd offer to come over and install new locks for you. Failing that, put a security chain on each door. They're even cheaper than locks. How about taking one or two of the strays to his house and leaving them there? A dead fish in his car?
