Ok. I'm a 14 year old girl and I've been using this technique for masterbaiting I made up for about 3 months now. When ever I feel the need to urinate, I lay down on my bed, on my back with a towel underneath me and just hold it in. I discovered by accident that this feels absolutly amazing and the feeling is there for a minute or so until it goes away. Then in about 5 minutes, the urge comes back and I just repeat the process. Usually my underware and the towel get slightly wet but I just throw them in the laundry when I finish. Even though I'm very satified with this technique, I've noticed that after about 30-40 minutes my lower regions begin to ache. I usually take that is a signal to get up and use the toilet and than I'm fine. Sometimes while I'm releasing it also hurts a bit.
I'm slightly concered about if this is hurting my body or not. Do you think I'm damaging my bladder my doing this? If not, can you explain my lower pains to me? I do this maybe 2-4 times a day and I would hate to give it up since it is so effective for me. I'm to frightened to try putting anything in my vagina yet until I get a little more confident with myself. Do you guys and gals think I should stop doing this?
Thanks in advance ^_^
