I feel so guilty for sending nudes without face

im 21 growing up in a religious family and country i was so horny and inexperienced had no boyfriend or girlfriend to sext with so i ended up posting in a r/ here and got punch of dms from men i answered like one or two but i bc i was so horny my mind wasnt working the way it did back then so i sent a close up pic of my boobs and pussy no face was visible thankfully its just a zoomed pic but i regret everything now and i feel dirty and weird for doing that ..can they also blackmail me with them or smth?? (I have ocd so i have stupid thoughts like this)
