Hi Lighteningbolt,
UTI’s are very common and can be caused by multiple factors. It would be really beneficial to speak to a health professional about it if you feel comfortable to do so. Either your GP, or you could visit your local confidential sexual health clinic for a check up?
If you feel like it might be helpful to seek some support or to talk in more detail about the sexual abuse you have experienced, you could contact Rape Crisis. They now have a live chat service if you could prefer to use that rather than call: https://rapecrisis.org.uk/get-help/live-chat-helpline/about-the-live-chat-helpline/
Or they have a national telephone helpline on 0808 802 9999. You can also find your nearest sexual abuse support service here: https://rapecrisis.org.uk/get-help/find-a-rape-crisis-centre/
Take care and keep posting,
Lisa
