Naughty Casual
The raunchiest section, blunt about wanting sex, and the one with the most women: about a third of its members. Visit Naughty Casual.

For adults only, 18+
Say what you want, find someone who wants the same, and keep it private until you are ready to meet.
Lots of people want sex without a relationship attached, and there is nothing wrong with that. The hard part has always been finding someone who wants the same thing at the same time, without wading through people who are after something else entirely. Casual.uk is made for exactly this: a UK site where adults can be upfront about wanting casual sex, and meet people who are just as clear.
Your profile says what you are looking for, from a one-off to a regular arrangement. Daily matches weigh that alongside distance, age and interests, so you see more of the nearby people who want something casual. No hints, no decoding, and no pretending you are after a relationship just to get a date.
Casual sex is better when it is planned like any other date. Carry condoms and expect to use them. Regular sexual health check-ups are free on the NHS, many clinics will post you a home testing kit, and a quick, matter-of-fact chat about when you were last tested is part of grown-up casual sex. If a condom splits, emergency contraception works best the sooner you get it, and PEP for HIV has to be started within 72 hours, so do not wait until Monday.
Consent is ongoing: either of you can change your mind at any point, and a good partner takes that in their stride. Keep your own way home, keep your phone charged, and tell a friend where you will be. Never send money or intimate photos to someone you have not met, and report anyone who pushes for either. Our safety page covers the privacy controls you have and more meeting tips, and the casual dating rules go deeper on etiquette.

AdultFriendFinder, running since 1996, is a big global adult network built around chat rooms, forums and webcams. Pure is an anonymous app where chats run on a timer. The big swipe apps are used for everything from a drink to a long relationship. Casual.uk sits somewhere else: a UK site made for casual dating, where your profile says what you want and nobody needs it explained. We compare the options openly, including Casual.uk vs AdultFriendFinder and Casual.uk vs Pure, on our comparisons page.
Prefer to start gently? No strings dating covers the whole range of casual arrangements, and casual dating near me shows how local matching works.
Casual.uk is a casual dating site for adults, and casual sex is very much part of that. You say on your profile what you are after, whether that is sex with no strings, a regular arrangement or a flirt to see where it goes, and your daily matches take it into account.
Put "something casual" on your profile and let distance do the work: matches lean towards people nearby, and VIP search filters by city and how far you will travel. Our near me page and city pages show where members are busiest.
Not to someone you have not met, however well the chat is going: anything you send can be saved and shared. You choose which photos go on your profile, and sending an explicit picture nobody asked for can be a crime in the UK. Anyone who pushes for pictures, or for money, is worth blocking and reporting.
