Im asking this question to any straight person here that had sex with different women or different boys.

Hmm... It depends, if I was to have sex with a girl I love it because we love each other. If it with other women most of the timeI look at as releasing alot sexual energy plus their got to be trust between the two parties.

What kind of feelings are you talking about? Physical sensations? Emotions? What am I supposed to be answering?

Chafing.

Im talking about the place that love take in a sexual relationship with differents persons.

I have no idea what you mean here by "feelings". The emotional attachment one may get by having an intense sexual night in bed with someone else can be an issue if you are swinging or having friends-with-benefits. I feel that is more of an issue with women than it is with men.

Want do you mean by having different feelings? Each person can feel different if that is what you mean. Everyone has different fetishes and are in a different place on the kinsey and kink scales. Kinky sex may be awesome with one partner and shite with another. It all depends on how much of your sexual interests are shared with your partner.

Are you referring to how to behave around each partner? Women have this psychological loophole in that all men have to do is act like that woman's dream man personality wise, though it is a great benefit if you looked like her dream man as well. Most women don't even know about this loophole, because men never even bother trying to act like their female partner's dream man. Then there is the issue on actually being yourself and wanting people to view who you really are and not some made-up fantasy illusion.

You're very, very wise.

Also, I believe it all depends on your sexual education as a toddler or teenager, when you're just developing.

What do I mean? Well, women are told to feel this when meeting that guy, and boom, they fall in love. Subsequently, people learn how to love and have sex, since it's not something you, shall we say, "posses".

My two cents.

If by "Sexual relationship", you mean f-buddies, then I can safely tell you that there's no love in it. Just pure animalistic lust. :P Those who play around are the same, too. Just one-night stands. No strings attached.

I had three different girlfriends in my past and
I had totally different feelings and emotions for
each one. Mr.XXX is right..
I had one night stands before and had no real feelings, just sex.

And that's coming from a girl who - I think - has a (sort of...) committed relationship currently, so that's saying something. XD

I'm not really that wise ... I mean I always preferred the company of adults over teenagers when I was a teenager, so it probably comes from that. And the fact that I always had the time to just think as I was constantly walking around alone.

And women aren't told to feel anything when they meet a guy ... I don't know where that came from. The rest you said is true, but not that.

Maybe I wasn't clear. Let me try again.

In most societies, parents tend to openly reject the idea of living a life as a single guy/girl. In my case, my dad says stuff like: "When you become a dad and learn how to deal with your kids, you'll understand". And they always tell me that the guy has to be, shall we say, more confidend and protective when it comes to relationships. They're very old-fashioned.

Well, the first part should be wrong, but the rest is right. I say should be as I don't look at other families in the general society. A parent should say that their child is free to pursue whatever makes them happy. Not everyone is set for a married life. I know I'm not.

HOWEVER, for parents, it is in their best interests to be married. An extra income, another view of things, swapping between the roles of "good-cop bad-cop" and never staying as one for too long. In marriage, the wife corrects the husband when he doesn't take into consideration the emotional values, whereas the husband corrects the wife when she strays too far from logic and becomes blinded by her emotion. The same thing applies to raising the child, and is healthy for the child to see both sides of the spectrum.

As for the roles of man and woman in relationships, that comes from the old medieval periods of how we dealt with relationships that stick with us today. Just like how the average person considers incest as wrong regardless if it is consensual, how we are just coming into terms with transsexualism, and how same sex marriage just recently became accepted, are all products of religion in that we discriminate against them due to religion being the norm.

This is one reason why I'm not religious. Religion runs on traditionalism, it conforms its followers to its traditions and will fight anything that defies its traditions.
