Do I have to have anal sex?

No! You must and should never do something you don't really want to do. In every form of sex, all partners should feel like doing what they are doing. You should also be allowed to stop at any time. Only do what you really want to do. If you are curious, you can also approach the topic slowly and talk about it with your partner.

I would like to try it, but my girlfriend doesn't want to.

Then respect your girlfriend's wish. Communicate with each other, why doesn't she want this? If it is because of fear of «accidents», but she would otherwise be interested, you can inform each other about the hygiene measures. If it is for other reasons, it is important that you respect each other's boundaries.

Will my partner get dirty during anal sex with me?

No, your partner will not necessarily get dirty during anal intercourse. The anus and rectum are only filled with faeces immediately before defecation, and are otherwise relatively clean. Accidents can always happen, however. The best way to ensure a clean rectum is through healthy eating. If you want to be completely safe, you can also use an anal lavage / anal douche to clean the rectum. However, this should not be done too often so as not to upset the natural intestinal flora.

What may be used during anal sex and how?

Basically, the same applies here as with vaginal sexual intercourse. Besides the penis, vibrators or dildos may also be used. It is important here that the same toys are not used for vaginal and anal use! Fingers play a special role in anal sex: you or your partner should use them to stretch the muscle before sex, otherwise injuries can occur. The best way to do this is to start slowly with one finger and then keep stretching with several fingers until the muscle is completely relaxed. During sex, it is then especially important to make sure that lubricant is used when inserting all objects, the member or even the fingers. The anus region cannot moisten itself like the vagina and must therefore be moistened with lubricant. The better this is done, the easier it is to insert the penis or a toy without pain.

What do I have to pay attention to during anal sex?

Good preparation and hygiene are the be-all and end-all here. The anal region can be cleaned thoroughly with soap and water. If necessary, you can also take an anal douche, but this is not necessary. Plenty of time to relax the bowel muscle is essential. However, it is also important that, whether with or without a condom, the penis should not be inserted into the vagina after anal penetration. Intestinal bacteria in the vagina can cause serious infections. So be sure to wash and also use a new condom when changing positions.
