My Man finishes too soon sometimes..

Hi everyone! I have been in a relationship with my man for 2 1/2 years and he makes my heart so happy. But most of the time he finishes before 5-10 minutes of me touching him, giving him BJs, or having actual sex. We are both 21 and he is uncircumcised. We love foreplay and experimenting, SO I was wondering if any of you ladies have tips to help him last longer! I have a latex allergy so we don't use condoms unless we buy the non latex kind lol. Can't wait to hear your replies!
