The vast majority of people who practice BDSM keep their fun and games strictly as a part of their sex life. There's also a significant minority of practitioners who have a kinky relationship outside of the bedroom but in a relatively subtle way; their dynamic permeates many aspects of their lives and is inherently part of who they are as a couple, but you wouldn't usually know it to look at them. A few, however, practice what is known as '24/7' - a lifestyle in which they are permanently in role and permanently overtly kinky. Couples who live this way usually have rituals, modes of address and acts of service that form parts of their daily lives. It's a reasonably rare choice IRL, but a very common fantasy for many kinksters!
Anyone with a vagina should consider investing in a set of Ben Wa balls. They're amazing: they feel great, they're good for your sexual health, they can enhance sexual pleasure, and continued use can even result in better orgasms. It's worth indulging in a little experimentation to see what works best for you. Generally speaking, smaller and heavier love balls will be harder to keep inside than larger lighter ones--start with an easy set and work up as your pelvic tone improves. It's also important to remember never to use vaginal Ben Wa balls anally; buy an ass-safe set and don't take the risk.
Let's face it, folks: breasts are pretty great. Almost everyone who is sexually attracted to women has a fondness for them, and plenty of other people besides can enjoy looking at them or playing with them. For those of us who have our own they're often a big part of the way we dress and the way we dress up, and people who think of their breasts as being one of their best physical features can have a lot of fun with dresses, corsets and plunge bras designed to show them off.
There's more than one way of getting your breasts involved in your fetish life, too. If you have a breast fetish, breast worship is a common practice amongst people who enjoy submitting to women, while those who get off on dominating them might want to indulge in a little tit torture or breast bondage. For most people they're a major erogenous zone, making them a great place to bite, suck, spank and squeeze. Just make sure you have the full informed consent of your partner before you get down to anything!
