Some consideration on my own opinion:

1) train your guy stamina

2) ask him to masturbate out before going for action

3) do not show much satisified are u during action.. so he will concentrate

4) Buy more sex toy.. so he can foreplay before action.. this can prolong time

5) Do not watch porn and masturbate at the same time. (Do it only when he really cannot take it after a period of time)

Hope all these advice can help you ^^
