Fiancé and I trying new things

We want to get married next year in June. We want to start out experimenting with crazy sex toys and swings etc. but once married we want to eventually find another couple to join us in bed. We want them to dom us and teach us how to be as kinky as possible. So far we just talk about it and imagine what things we’d do with them while we have sex. Tonight we talked about me being blind folded and getting fucked by another guy while my soon to be hubby watches. We want the guy to cum inside me and then watch while I get fucked by my man after. Once we start this new sex lifestyle, I wonder if sex with just the two of us would be different or boring afterwards. Or if one of us will regret it and want to stop. But for now, it’s been hot to imagine and fuck to the thought of.
