Female led relationships discussion

I’m planning a trip to buy toys and wanted some input before making the purchase. I have my sights set on a strapless dildo—specifically one that stays inside me while presenting another end for him. I really enjoy that close, intimate connection when he’s getting his anal pleasure, though there are plenty of options available. Another option is the type where it straps into his mouth. Anyway, I’m trying to weigh the pros and cons before committing. Any advice would be greatly appreciated.
