Butterfly use with intercourse?

[Ruby]

Is it safe to use a butterfly vibe during sex?

I don't see why not, as long as it isn't being slammed into you, bruising the skin, etc. And since you're tied up, if you use a vibrator - of any kind - on the clit , please make sure that your partner knows when you need it to come off.

The pleasure can turn to pain when that sensitive area of the body gets way too much stimulation.

Shopping on the Internet is a great way to go.
We have a thread around here with a list of fun stores you might want to review.

Yup, found it:
