Does anal sex cause anal relaxation? (Sexual knowledge adult novel)

[Questions and Answers]
Xiaoqi: My boyfriend and I often have anal sex. Will frequent anal sex lead to looseness? Will I lose control of my bowels?
Dr. Shuang: Xiaoqi, anal sex is a dangerous behavior. If you get used to it, the inner wall and muscles of the anus may over-expand and bleed when the penis enters, which can easily cause bleeding or even transmit sexually transmitted diseases. The anus is not a sexual organ, does not secrete lubricant, and has poor elasticity. During anal sex, special attention should be paid to strength and hygiene, and the use of condoms is necessary.
Xiaoqi: If I do this for a long time, will my anus become loose when I get older?
Dr. Shuang: If anal intercourse is not frequent, it should not cause anal relaxation, and it has nothing to do with age.

Xiaoqi: How can I keep my anus tight?
Dr. Shuang: Actually, if you stop anal sex and keep doing proper exercises, I believe the anal muscles will recover normally.
If you still have doubts, it is recommended to seek medical advice immediately.
Xiaoqi: Sometimes the anus becomes very dry. Is it appropriate to use saliva as a lubricant?
Dr. Cool: Using saliva is very unhygienic. It is recommended to use condoms and water-based lubricants throughout the process. Oily lubricants are more likely to cause skin sensitivity and may also damage the structure of the condom due to chemical reactions.
