While rummaging around last night I found this site. It`s a section of the GMFA site which is a charity specialising in the health of gay men.
The “How Risky Is” section is really great. Well written, informative, but not prescriptive or full of impenetrable jargon. It tells you what you need to know about various sexual activities and how to ensure that you play safe.
I`m really taken by the site, it`s bright, informative and user-friendly. In addition to the sex and sexual health advice you`ll find information about the gay scene and various groups from clubs to those that aim to look after your physical and spiritual well being.
Remember, the site is a charity so if you can, please help them with a small donation.
