Is it normal that my boyfriend gets turned on when i cry, or i'm in pain?

it could be like a sub-concious power trip thing. like your crying makes you vulnerable, which in contrast makes him feel powerful. and when men feel powerful they want to dominate? idk, its one possibility.

This is definitely not normal. You can either tell him that it bothers you and you do not want to do anything sexual when you are sad or get out of that relationship. Sounds really unhealthy.

That's not cool :/

He is a sadist if he's also posessive, i know because im the same. Having ASPD is part of the reason it developed in me but yeah the enjoyment isnt actually from causing pain but seeing it expressed in someone (especially on the face.) We are actually not as rare as you'd think, there would be atleast a few male and female sadists on this site. Nothing you can do though, he's hardwired like that for life. I knew a female one that saw a friend of hers just smile at her bf (the sadists)...she walked over to the friend said a few quiet words to her and she looked nervous the rest of the day. I said what was that about? Miss sadist replied "i dont like people touching my shit". Just ask yourself if you can put up with it, some can. EVERYONE knows one though......

He's sounds like a sadist;)

Sounds like a rapist in the making.

Speaking as someone who has dated a sadist for 10 years I think there is a lost of anxiety here that is being expressed because of a lack of experiance or knowledge into it.
Firstly re your boyfriend getting turned on when you cry- there are reasons other than sadistic enjoyment that could cause this. There is a type of fettish towards crying that some people have.
There is also maybe quite a sensitive answer that may be seem less extreme to you (and some people find this quite endearing) which is that when you cry or show pain in front of him you are showing a vulnerability which in turn makes him your protector- and can make him feel more manly which comes out then as sexual arousal.

If he is sadistic that is not necesarily a bad thing either.
I have dated- prior to my current man quite a few "normal" types who have emotionaly really hurt me.

This man who actualy enjoys my pain is so incredibly respectful of me that I would take a bit of physical pain any day just to please him.
He absoulutly never ever has taken me for granted and he has been the most supportive person in my life.
He does get aroused when he hurts me (ie gives me a spanking) but I find it incredibly arousing that he gets turned on by doing this to me so win win.
I'm not so masochistic really- I would get turned on by anything he did to me that turns him on- so if it where a massage then that would do it for me also- but pain is his bag. I love him, I want to please him and on ballance the physical pain is nothing compared to the emotional anguish I have had with past boyfirends who would never have been truned on by hurting me and yet so casualy left me with emotional scars. When my man hurts me- (and I absolutly have to stress here that it is not abuse- it is fully consensual on my part, if it was non consensual then it would be abuse and that is not what I am describing here)- he can be quite rough- but having his focus, his attention on me is very intimate. And if he makes me cry in the process then he comforts me afterwards - showing me how much he cares and appreciates my gift of submission to him. I expect that a fair few people reading this may jump to superficial conclusions about me and my man but there are a huge number of people out there who think like me. See BDSM there is a lot of evidence to support this type of relationship and it seems to me that the biggest reason they can be so succesful is because they really foster an environment where discussion about intimate details becomes a very normal part of the relationship allowing for excelent comunication in a relationship.

My advice would be to actualy talk to your boyfriend- in a non judgemental way- if he gets turned on by pain so be it- it doesnt mean you have to expreiance pain for him or that it will translate into him being violent to you.
Let him know how seeing him aroused by your pain mkaes you feel also- it may be that he isnt aware of it- he may feel that him wanting to make love to you is a way of showing that he cares deeply about you.

Keep an open mind, communicate clearly and respect each other.

Take care

I knew a guy who would cry whenever he saw a girl cry... very different than this...

It sounds like he feeds off of vulnerability and needs to be the one in charge, but at this rate, it sounds unhealthy.

BREAK UP WITH HIM IMMEDIATELY!! the fact that he likes it when ur in pain shows that he doesnt care about ur safty or feelings at all. BREAK IT UP!!

LOL this cant be real. I think his brain wiring could be crossed.

not necessarily rapist. more sadist, getting off on someone else's pain. does he have the same reaction to other people being in pain?

I've never heard of this before by it sounds like he is a saddest. Getting turned on by your pain is definitely not normal. I would run now! As fast as your can!
