I don't think he'll freak out most guys love to hear what their girls fantizise about
I totally agree. When my fiancee and i first started dating he was my first and I was his second so it wasn't like both of us had years of experience behind us. He had an idea of what he wanted and I didn't have a clue. I however didn't want to seem clueless. So I started reading erotica more for ideas on what to do and trying to figure out what I liked and wanted. The stories with bondage and spanking got me the most excited. So then I printed out an article on how to have a proper spanking and saying thank you master after each slap and asked do you want to try this. Lo and behold we both had a grand time with it. He didn't think he would and I think initially the realization that he enjoyed slapping me scared him but we enjoyed it too much. In case if he doesn't respond favorly I may suggest giving him some time. Initially both of us were against threesomes or introducing other ppl in the equation. Then somewhere along the line (through constant communication and sharing of fantasies) we realized that the idea of threesome did appeal. Something changed and we're not sure when. Now i personally would love the idea of two guys and me but at first he found the idea of another guy uncomfortable. So I was like that's fine our third could be a female. But recently he said he wouldn't mind a guy. I thought he was saying that to make me happy but he guided my hands to his equipment and he was genuinely intrigued by the idea of another guy as well. So goodluck and sometimes the initial reaction isn't neccessarily what ends up sticking. Opinions grow and change and as long as you guys communicate wants and needs you'll be fine
