Orgasm after vaginal birth!

So I'm about 27 days postpartum. I know- no sex. I haven't had any. Believe me, I can't even think about sex. I had an episiotomy so sex sounds brutal. I'm still healing. BUT- and that's a big but... I tried masterbating. I couldn't hold out any longer. I used my soft bullet . It felt fine - it felt great actually... Until I had the orgasm. Uhhhh can I just say- OUCH! My clitoris feels sore now. 
Am I alone?
