I have spent time(and still go on vacations) to a not so distant place from Saudi-Arabia. Where the rules almost match regarding pornography and explicit content.
The ISP's mainly dont log(or block) P2P traffic. Only http is their main concern. Everybody uses P2P as they see fit for their needs there. You can use P2P without any fear. Everyone does. Although excessive usage on your part might alaram the admin and he could chose to look into the matter. But it's always safer to not-use anything that can be tracked. Use encrypted traffic, ssh tunneling, encrypted VPN, JAP(No flame please) or any other means of secure transfers.
Side-Note: Most people use proxies on uncommon ports to bypass certain ISP bans on pornography. That is highly advised against to you because of severe http scrutiny by the officials, or those who bring in effect the rules.
