<human>: My boyfriend and I have been together for about a year and a half. Our relationship is strong and happy, but lately my bf has expressed that he wants to be more sexually adventurous and push some boundaries, specifically with bondage stuff and a threesome. I have low libido in general and am pretty vanilla when it comes to sex. I really do not want to have a threesome and I don't think I can be a dominatrix or whatever.  My bf has not expressed much frustration about this and always reassures me that he loves me when I show hesitation about trying these things. Basically, he isn't the problem...my own guilt is. I feel really really badly that I can't give him what he wants and although he reassures me and is very sweet about everything, I know he really wants to try these things. 
I want him to be satisfied and be able to try new things sexually. Lately I've been thinking that I should give him permission to seek out other partners who are more sexually compatible with him to experiment with. Problem is, I would be really jealous and I don't really want him to have sex with other people. I really don't think this is worth breaking up over. What do I do?

Give me the gist of the text in a nutshell
<bot>: boyfriend wants to be more sexually exploratory than I do. This is causing me a lot of guilt. Should I give him permission to explore with other partners, even though this would cause me quite a bit of jealousy?
