Hi, I am new at the forum, I am a sub, currently wanting to have a first experience in the bdsm.
Any tips for someone like me?
I already use some toys like dildos and buttplugs, but I had a lot of fear of trying things like gags and handcuffs, I mean, I want to be dominated but I am pretty scared of about what would happen if I trap myself, specially because I live with my family and I am the biggest daughter of the family...

Do the Kenny & hang yourself

Have a safety word in case your second personality kicks in and tries to murder the first one

Slip on a banana peel clumsily and you will tumble into and entrap yourself in your bondage equipment. Trust.

I haven't fooled around with self-bondage, so I can't answer your actual question. But I have had a lot of fun dominating myself with solo painplay, which is great for someone who wants to explore with low risk (it's just you, of course you're going to stop yourself before you cross your own lines). Floggers and clamps can go a long way, and there's always temperature play.
