I suppose if one had a choice between say, erectile difficulty, premature ejaculation and retarded ejaculation. Retarded ejaculation would be the one to have, at least from the partner's point of view.
The profile of this dysfunction and those who have it tells the whole story.
Super attentive lovers who focus entirely on the pleasure
of the partner.
Because of their low self esteem they can only feel worthwhile
during sex by leaving their partners completely satisfied (and exhausted)
Will make love like Don Juan to women who he is not even aroused by (especially those women) and can carry on marathon lovemaking sessions trying desperately to prove his expertise as a lover despite his unaroused state.
He manages to get and keep a hard erection that can last for hours and, under circumstances where most men would not be able to get an erection at all ie: in a completely unaroused state.
Outside the bedroom he is usually a kind, sensitive and loving companion who avoids stress or arguments in the relationship even if he is full of rage and resentment at his partner's easy orgasms and sexual satisfaction.
