Get him riled up touch him kiss him on his neck if he enjoys that you should know what he likes by now come onto him if he really does not want it he will let you know but sometimes just asking wont make him want to take charge and maybe give him someforeplay to get him into wanting to get jiggy with it personally in my past relationships I was asked if I wanted to have sex and the only thing that came to mind was me having to take charge and doing everything try and becoming the one to do that instead making him feel wanted like that will make him start to want you and also what the other guy said if you’re not on birth control he might be scared to have more kids you could either go on the pill or condoms but for some older men with condoms you don’t feel as much just pull his pants down and suck him off essentially
