@shewolfnm,
I think it does hurt, but you have to get a little older to realize the extent of the injury you have done to yourself... Sex is great, but intimacy, even in love, even in marriage is terribly dangerous, and in a sense, exhausting... We either do it abandoning ourselves to the kindness of strangers, or we do so with some limited measure of trust, and that makes the sex great... It is our secret, and you won't use my love of you, and my surrender to you against me... That is what I mean, and it is so much better...
One of the greatest injuries of casual sex is the total waste of time... The young think they have plenty to waste and are wrong... Relationships in the ideal return far more than is put into them, or rather, what people put in they have in excess, and what they need they have but little of... In any event, the goal whether recognized or not of all the sex sampling is a mature and fun sexual relationship that becomes complete and monogamous... It is not wrong so much as counter productive to spend all ones cooking time in the meat market... Take it home and set it to broil...
