newfound secret

i was always so sure about myself until last week when i admitted to myself that id been secretly into dd/lg stuff for years. it kinda hit me outta nowhere one night while reading a forum thread on the topic. and now im scared and confused because i dont know if its normal or just some weird thing only i do. we had this intense fight with my partner, but then later after calming down, he seemed ok with me exploring this side of myself as long as hes in control. it feels so liberating to finally let go and embrace this part of me...but im still not sure how to move forward without freaking out or screwing things up. anyone ever feel like this? should i even try bringing this more into our relationship?
