I haven't had an Orgasm through sex for ages and ...

I can't say that I know the exact answer to that question, but all in all it sounds like he just either doesn't have that drive with you or he doesn't appreciate you as a woman.  There could be other reasons too, but I'd have to know more about the relationship and how long you've been together.  If it doesn't change though I don't think that it's fair to you at all.  You have a right to be happy with your significant other and if he doesn't care enough about your feelings to do something it might be a good idea to find someone else.  Be strong, talk to him about it, and if worst comes to worse find a better guy to be with.  I hope that I could help, good luck :)

everything about reaching orgasm:

When a woman never has an orgasm while making love and is distressed by this, she may have an orgasm disorder. When there is sufficient desire for sex and the body is stimulated in the right way, then an orgasm is a reaction of the body. For most women the orgasm is caused by a direct or indirect stimulation of the clitoris. In general, vaginal stimulation is not enough to get an orgasm. One third of all women rarely or never have an orgasm while making love. Only one woman in ten always have an orgasm when making love. Some women are also less interested in getting an orgasm.

What is wrong?  Where to start... hmmm.  Let's start with the porn.  Your boyfriend prefers pornography to a real girl friend.  That is your first problem. He doesn't need you.  He has his own hand to keep himself satisfied.

Problem #2.  You are not only tolerating that behavior (which I wouldn't, don't, and never will) but also are allowing it and being party to it.  Some women feel that porn is okay.  The hard truth is that it isn't okay in a relationship and will never be. The guys may try to sell you another story on that one but it won't change the facts.  Two people in a loving, committed relationship rely on each other for their wants and needs...not the image of some stranger.  It not only doesn't help a relationship...it hurts it.

Problem #3.  You are giving him a 'hand job' or a 'bj' ......why?  We are talking about the guy who has no intentions of pleasuring you and every intention of pleasuring himself.  Why are you helping him out?  If he wants to pleasure himself so badly...let him.

Here is the bottom line:  He is only interested in himself.  He has no respect for you or the relationship and he certainly isn't interested in your wants or needs.  As my friend Equus would say... he is using you and the porn as a tool for masturbation.  Who needs it and why on earth are you putting up with that?!

Dump this idiot.  He doesn't care for you.  Find a guy who does care and move on.

PS... I don't buy into the orgasm disorder theory a whole lot myself.  Find a real man who knows how to pleasure a woman (instead of himself) and you just might find yourself enjoying the sex when you do have it again...just don't forget to dump Mr. Wonderful 1st along the way.

Good luck,

PSS.  One would have hoped with all the porn your bf's been watching, he might have learned something.  You might want to mention that on your way out the door. 

What's wrong he has absolutely no respect for you , NONE .  And you are not only allowing him to disrespect you , you are engaging in behavior that promotes it .

Sexual intimacy between a man and a woman is a gift in a committed relationship , that should not be shared with another . His behavior is far from intimate .  It is no longer his desire for you  it is his need to gratify his desires brought on by viewing and or engaging other women .  YES as Jada said ,  It is of my opinion that you are nothing more than a tool for masturbation . This is emotional infidelity . This man is engaging in amorous adventure outside of the relationship ,  he is removing himself from the commitment he made to you . 

 I would kick his butt to the curb in a heart beat .  

 Find a man who will love you ,respect you and does care about your feelings and needs in and out of the bedroom .  This man isn't that guy .
