Talking the boyfriend into being tied up?

Find a local rope bondage enthusiast group and take him to watch. A friend took me a few weeks ago and I completely fell in love with rope bondage. A quick search on FetLife should find you some resources.

Aside from CafeSabroso's advice, you could also atart out with the really non-intimidating stuff like a basic ankle or wrist tie to get him used to it and slowly move on from there.
It can be scary to someone that isn't sure if they'll like it or not so a basic tie (or cuffs, depending on what you two prefer), done in a secure but fairly loose manner can be a gentle way to introduce it.

I will tell you a little story about what I did to my husband. He likes to be tied up but me not so much. We sometimes have a crowded house so it's not uncommon for us to go someplace in my excursion and get busy. Being a huge vehicle it has more then enough room if you take out the third row seat and fold down the second for a full size man to be laid flat and tied down in the back of it to the super convenient cargo tie down points . So with his cooperation of course I tied him totally naked in a spread eagle four point in the back of my truck and took him for a drive. Now I know... safety safety - well no it wasn't a seatbelt but he was more secure then anything in that vehicle with the number and size of straps I used. So to make it really interesting he thought why not go blindfolded and with ear plugs in - the whole sensory deprivation thing. So basically deaf plus the stereo on loud, with his blindfold on over the eye mask to make double sure he couldn't see a damn thing I took him for about a two hour ride. Yes... naked totally and erect for about 90% of it. At my first stop I climbed in the back and ran my nails up and down his tummy and around his balls and gave his shaft a couple little strokes. Some light kisses to his cock followed by more nails up and down his thighs and some judicial neck nibbles and we were back on our way. Next stop a little more along with some really sloooooooow head and ball sucking followed by me lowering my now super wet pussy to just the tip of his lips for a taste and off again. This went on for probably ten stops before I fucked him till he came inside me and then sat on his face to return his lovely cum back to him. Each stop led to a little more naughty and included some light whipping with a little whip I have, bitting, nails and kissing. Also a little ice cube rub up and down his body which damn near caused him to have a seizure. Tip for you boys.... If you are really super ticklish don't let your woman tie you up cause we know where every single one of those spots are. I did get some good pussy licking from him and did 69 him a couple times but never long enough to let him cum before I would get off and drive again. Also boys... the rear AC gets really cold when your nekid under it and tied down (Shrinkage and boy do the boys suck up tight)

Couple days later repeated but brought along a girlfriend of mine Who got to watch and play a little - guess which mouth and guess which pussy it is baby???

Anyway tell him you won't hurt him unless he asks and make sure if he freaks or wants loose you immediately let him go. Some people, me included, don't do well being tied up or down, or are completely claustrophobic so if he really isn't into it see if maybe he will let you just ties his hands together but keep his arms free the first time and just go super slow and in stages. It might not be for him and that is ok - just let him tie you up and take you for a naughty ride in or out of the bedroom XOX Creamy

If you have any other questions please feel free to email me - not that I am in any way an expert - I just try all kinds of wild kinky shit.

Forgot to add - have him pic a safety word and if he says it then hes untied immediately with no argument or questions asked. ALWAYS tell him thank you for helping to fulfill a fantasy you have and how much you enjoy/enjoyed doing it and how much it turned you on. Stroke his ego not just his cock and be sincere and mean it when you do. XOX

HOT story!

Great advice, non intimidating items would work best first.

I was going to suggest this.

one thing that id love to be tied up for is teasing. Start out with something simple tell him youll only do a strip tease (or just something you know will get him wanting to jump your bones) and work your way from there... also start off with like using a scarf or tie to lightly tie his hands somewhere comfortable. Hopefully he finds himself in a rush to jump you and will start being more accepting of it to the point were you can tie him down and have your way with him =P
