My boyfriend is aggressive in bed?

If you don't know exactly what your limits are yet with this type of play that's fine, but start talking. NOW!

You need to open lines of communication immediately with this man. He thinks you "generally like these things in bed" which is encouraging him to explore his limits and take you for the ride.

Unfortunately he's on his own private ride which is why you are confused and scared. It sounds like more of an 'out of control' thing with him right now.

Discuss and agree the rules and boundaries for play well beforehand (in writing if necessary - a lot of players use a safe word traffic light system 'red'= stop right now! 'Orange' = don't escalate, 'Green' = all good).

Make it crystal clear his excuse about getting caught up in the moment is selfish, disrespectful, unsafe and UNACCEPTABLE. That bullshit cannot happen again! A good dom operates with care of their sub front of mind at all times. He should be checking in to make sure you are okay with whatever is happening.

BE PREPARED: If he doesn't have the mental discipline to dominate and meet a consensual level of play, you are putting yourself at risk with him. Go with your gut. If in doubt taser his ass!

If you are with someone who it takes a couple trys to get to stop every time then the last thing you want is to be with that person tied up and defenceless

Next time he gets rough with you, subtly reach for his balls and squeeze the hell out of them, not forgetting to twist and pull them at the same time! I am sure he will get the message...

Normal for a male to be dominant, (somewhat) aggressive, controlling, and to have fantasies about tying you up.

He does have to learn though that YOU as the submissive, actually get to set the limits, NOT him. A friend of mine (who is apparently into the BDSM scene) recently expressed it to me as "sub needs, Dom needs, Dom wants, sub wants - in that order at all times". I found that quite insightful.

Sort out what you "Need" and what you just "want", talk to your boyfriend, sort out some sort of "safe" word in case he oversteps the line (and make sure he understands if you "call safe" and he doesn't stop, you will be immediately dumping his stupid ass), and see where it goes. You never know, you may just take your relationship with your "Master" to a whole new level of pleasure.

That's all about control and to escalate it without your consent proves he has no respect for you and you could well end up in physical danger. You need to get him out of your life ASAP.

Then you can look for someone who will play the sort of games you like in bed on a consensual basis.

He sounds fucking awful! Put on your ASICS and RUN! Who cares about what turns him on or his stupid fantasies! Dump him, he's a complete bastard!

You got what you asked for

Im a gentle person, you have Whatsapp?

Call me old fashioned, but I just don't get the idea of anyone wanting to choke the one you (supposedly) love during sex.

Next time he starts choking you , give him a hard knee right in the nuts { gonads } and I guarantee that he will cease and desist immediately and permanently.
He probably wont be able to have any kids after you do that , but who cares ?
His nut sack will be deflated permanently and they will look like 2 dried up grapes { raisins }.
They will look like somebody stuck a pin in them and popped them and let all of the air out of them.
Then he can hang them on the Xmas tree because they will only be ornamental anyway and they wont be any good for anything else.
Then at Xmas time you can invite your families and friends over and tell them look what you decided to do with his balls , make them ornamental because thats all they are good for.
While you're at it , do what Lorrena Bobbitt did and chop his cock off and throw it in the ocean so they will never be able to find it to sew it back on.

you should use a safety word, idk, like "peach!"
make sure he agrees with the bdsm terms, this kind of things must be done under a certain scope, or it can slip off your hands

That's normal, but tell him to stop. Or just break up...?
