Please help - I am disabled and have a carer come in the morning to help me to the toilet and to get showered etc.

I masturbate a lot and know the time the carer comes in so I can do it in time without her knowing. After masturbating I always need to wee urgently so I have to time it right, when I get on the toilet the carer can hear me and comments at how long I take to wee, when it eventually comes I wee for ages and it amuses her, as it is so noisy but after waiting all night and so desperate I just cant help it. I have asked her to leave me on the toilet and do something else for a while, but on occasions she has come back in only after a few minutes and found me rubbing myself as I didnt get chance to before I hoped I could give myself a bit of private pleasure.

The most embarrassing time of my life happened the other day. I woke up really early and needed to wee, but knew I could hang on, and maybe even masturbate before the carer arrived but it would be a long wait. I had to masturbate as I was really horny and couldnt wait any longer, even though it was 2 hours before she was due. To my horror as I was in full swing and at the point where I could not stop and enjoying it so much, she walked in and found me in that state, she came earlier as the shift rotation had been altered. I nearly died of embarrassment, she ran off back downstairs for ages while I cringed in bed, also by which time I was desperate to urinate, as I always am after masturbating. I waited for about half an hour absolutely bursting and crying in pain, and I hadnt got anything to wee in, it got to the point of panic, I called out and she didnt hear me and I wet myself. Then she finally arrived and embarrassed me about what I had done, I am so upset I now avoid masturbating which is making me thoroughly miserable.

Is there something I can get to wee in when I get that terrible urge, so then at least I can masturbate in the night in private. I dont want to discuss such a private thing with my carers.
