We use my toys BEFORE sex, but never while actually having sex. I don't think I'd find a vibrator AND my partner inside me to be very.. pleasurable. Really, it'd be uncomfortable for me and I don't ever need extra. Using a clit vibe can be fun during sex, but I haven't found one that isn't a huge hassle so we don't do that often. We just leave the forplay to foreplay. I'd like to find a good clit vibe for that purpose though.
