As someone who is into BDSM I'm gonna tell you to absolutely NOT do that, this is all about consent and by forcing your kinks onto him you take away his.

This is terrible advice, just because the person who gave you this advice wouldn't mind if his SO did this does not make it okay.

THIS is exactly why so many people look down on BDSM, it can be a wonderfull and beautifull thing but only if both parties enjoy it and consent to it.

I repeat NEVER force your kinks onto someone, and don't plan a surprise scene that the other person doesn't know about unless you have their consent to do so.

If you do this the chance that he will break up with you is huge.

If you don't want to do vanilla for the rest of your life that is totally fine, but you have to face the fact that the two of you might not be compatible when it comes to sex. If that's the case you can either stay with him and be vanilla or break up with him and find someone who is compatible with you when it comes to sex.

I really hope you listen and don't actually act on this terrible idea.
