How can I keep my boyfriend from having to long of an erection from sex? Like sex is good but it last so long its not good at the end and I just don't want to have sex anymore cause of it. Any advice on what I can do?

You can try more foreplay so that he is closer to climaxing before penetration.

You might try varying positions and angles and/or taking breaks to give your body other sensations.

Other play doesn't have to stop once penetration happens. Be honest with him about your needs and what you are experiencing. It doesn't mean he is a bad lover. It means you need to experiment and see what works best for both of you. Part of sex is learning what each other needs, likes, and dislikes, and how to blend them into a pleasurable experience for both of you.

Ok thank you
