Me and my boyfriend have unprotected sexHe took my virginityWe have never used a condomIm not on the pill He has had 4 partners Should I worry about sexual diseases?

Yes, it's important to be concerned about sexually transmitted infections (STIs) when engaging in unprotected sex. Since neither of you are using protection and your boyfriend has had multiple partners, there is a risk of exposure to STIs. It's advisable for both of you to get tested and consider discussing safer sex practices moving forward. Additionally, consider consulting a healthcare provider about contraception and STI prevention options.
