I gave this option in that other post that hotasfrick was talking about.. But what I do with my boyfriend sometimes, is when im giving him a hand job or something.. I go until hes about cum, then I stop... Wait a couple seconds until hes calmed down, and go again.. I repeat this maybe 3-4 times...He gets mad at me for doing this, but I don't tell him why im doing it, and plus eventually I will finish, and everything will be fine again.. Haha.. By doing this occasionally, eventually he might get better at controlling himself, and being able to hold out even longer.
