I don't often read this column, but now that i am here would like to make a comment.
There are two sides of relationships, physical and mental.
I want to talk about what happens, if a man is aroused for longer time, but will not ejaculate on the end of it.
It results enormous pressure in man's sex organs as his system is getting ready for action, but the "action" never happens. This condition can be a painfull experience and can last for several hours after. My own experiences included behavioral disturbances, like anger reaction few times.
It is important to remember, that sexual arousal releases hormones in the blood, so the man can last the "distance", when the "action" starts!
It is your choice not to have intercourse, but if you "play" with him, give him a change to ejaculate on the end.
I hope this gives you something to think.
Good luck to you!
