What can I do? Im a very sexual person and am down to try almost anything in bed while my bf likes it more vanilla. He told me he doesn't like all the kinky stuff. How to get him to think outside the box?

Take turns - first time you do it all his way, next time do it all your way. ;)

Start off with something new, but not necesarrily kinky. Then gradually add new things in the bedroom (or maybe the kitchen?), you aren't going to go from missionairy to BDSM in one night if that is what you were hoping. +3

sometimes trying to fit the square peg in the round hole just doesn't work ... you may end up being so unsatisfied that you decide to look elsewhere ... determine how important your sex life is to you and then find someone most compatible with your desires

The idea is it's suppossed to be fun for both.
.
Can it be fun for someone if he/she is being forced to do something he doesn't want to?
.
He likely WILL want to please you, so he may be willing to try new things, if only for you, as long as you don't press too hard and too fast.
.
I wouldn't expect too much though and, ultimately, it wouldn't be fair to ask for that.
.
As an example, let's assume he had sadistic tendencies while you were not a masochist.
.
Surely it would unreasonable for him to expect you to submit to torture just to please him?
.
You give no infromation on how long you have been together, how compatible you are in other areas. Sexualy, however, maybe you are not all that compatible sexually?...

Are you playing dom or sub? He might be more amenable if you are the sub. At least for awhile. ;)
