Marriage Question!!

Me and my husband have been married for almost 6 years. Before we got together we both had our fair share of relationships (me more than him). Soooo I’ve noticed no matter what i do or how much i insist on how i like things in the bedroom he can never fulfill what i want and need. I mean he tries but i guess he thinks he will hurt me or something (that’s what he says when we have talked about it). I don’t know if it’s because he’s inexperienced or what. It’s like he’s vanilla in the bedroom and I’m sherbet. Complete different side of the spectrum. Does anyone else have these problems? Advice or ideas? And no leaving is not an option he is the love of my life, plus he signed the damned paper he’s stuck with me. Lol
