My boyfriend is not good at that, and he won't be able to do it after a few moments. I still love him very much, what should I do?

This kind of thing is mostly caused by psychological reasons. You can use an excuse to ask him to wear two condoms. The excuses have been thought of for you. You will feel more comfortable with two condoms, and at the same time, you will feel better. To encourage him more, just say you are great, etc. You can even pretend to have an orgasm and look satisfied. After your boyfriend feels that he has succeeded once or twice, his self-confidence will increase, and he will be able to wear less condoms. Gradually, he will no longer be nervous about this, and he can last longer.

Another point is to try to let you take the initiative and use the position of woman on top and man on bottom. This will make it easier for you to be satisfied, and at the same time, your boyfriend will not reach it so quickly
