um, well you can technically have an STD/ STI and still have safe anal sex. Just saying. I would listen to everyone above. Take your time, have lots of lube, and have an open line of communication available at all times.

As others have said, it's just important to prepare properly and keep relaxed. Seriously, really relaxed! Make sure you trust your partner, use plenty of lube, communicate, and don't be afraid to take plenty of time. You may want to start using some toys first, to get warmed up a bit!

I feel like it is safe. Unless you go from anal to vaginal.

Being clean of STDs is a great first step for safe and fun anal play. But it can still be dangerous so caution is important.

1. There is a chance at tearing the anal tissue so use plenty of lube, go slow, and communicate well.

2. Even without STDs, there are bacteria that live in the anus that help to break down feces and kill foreign bodies. It is possible that some could find their way into your partner's urethra and cause an infection. I know most couples don't think of using protection for anal sex when they're not using protection for anything else but it's worth considering.

3. The woman could get an infection if some of those bacteria mentioned earlier find their way into her vagina. So do NOT "double dip". If you want to switch back to vaginal sex after trying some anal, wash it first and/or wrap it up in a condom!

But despite all of that, it can still be fun and satisfying. Just be safe and be comfortable with each other.

Just go slow and dont break the skin

It's dangerous if done wrong, my boyfriend and I are monogamous and both clean and have unprotected vaginal sex all the time but we still buy condoms for anal. The anus is an area for waste products, plain and simple, and it's better to be safe then to risk infection. Also the anus is not self lubricating so like they said above, use lots of lube, and when you think you have enough add more. There are two rings of muscle around the anus, one which you can consciously relax and a second which you cannot. He needs to go slow at first and you need to be comfortable telling him to wait every time it hurts, pain is your body's way of telling you something is wrong. If it starts to hurt wait, give your body a chance to relax, and continue. Also as others have mentioned NEVER go from one hole to another because you'll transfer all kinds of bacteria. That's another benefit of using a condom, if you decide you don't like it he can just pull it off and proceed vaginally. Also it may help to warm you up with a few fingers or a small toy before you start (but make sure any toy has a flared base because it can get sucked up there). A lot of girls get off on how taboo it is and it is also possible to reach the g-spot anally.
