What is boyfriend wants to use condoms all of a sudden?

There could be various reasons why a boyfriend may suddenly want to use condoms. Some of the possible reasons include:

2. Pregnancy prevention: Another reason why a boyfriend may want to use condoms more frequently is to prevent pregnancy.

3. Health concerns: Sometimes, a partner may have experienced symptoms such as a rash, discharge, or other signs of infection which may have led them to want to use condoms.

4. Trust issues: It's also possible that a partner may have cheated in the relationship, and as a result, wants to use condoms until they can prove that they are STI-free.

5. Sexual preferences: Lastly, some partners may simply prefer the sensation of sex with a condom, or may want to experiment with different types of condoms for added pleasure or variety.

Regardless of the reason, it's important for partners to communicate openly and honestly about their sexual health and preferences, and to make joint decisions that are in their best interests.
