Can a submissive be with a submissive?
This is a difficult question to answer because it differs for each BDSM relationship and what works for individual people. I don't personally recommend this but if you do end up dating another submissive I hope this helps!
This relationship dynamic would be very difficult for both people unless one or both partners are a switch. A submissive wants to be dominated and looked after therefore the relationship between two submissives could be hard to handle.
Some tips for two subs would be sharing cute snacks, playing together in little/pet space, giving yourself rewards/punishments since your partner isn't comfortable doing it, etc. Another tip for submissives in a relationship is to think about experimenting with switching roles as neither partner will be able to support and give the other what they want/need, or even maybe finding dominants outside of the relationship.
What do you think? Would two submissives be able to handle a successful relationship?
