A polite 'thanks but no thanks' doesent always work.
Just chill out and ignore the impolite ones and enjoy the site.
On a site such as this, its inevitable you are going to come across people who do not know the meaning of the word no.
No point in getting angry, for every impolite person, you will find lots more who will respect your bounderies.
Stick with it dont let them get to you.
i ask a smilar question on here a little while ago and got some very positve replies but i think the most direct and probaly the most truthful was its because you have tits most of the guys just look at the profile see and get in touch now i have got to know the repeat offenders names so i just delete without even reading what they have to say or you can always block them dont leave the site though as for every pest theres a lot more nice people
I report repeat offenders.
It's alright saying "chill" but I tell you single straight males, you go on cam in a gay/bi room - you don't even have to get your cock out. See how you cope with the constant whispers, directing and then, when you don't respond, they get abusive!
Good luck with that.
