Dutch girl who takes risks

Hello I hope people can help me. I am a good looking Dutch girl aged 38 and whilst I really want to settle down and have a family I am addicted to casual risky sex. My addiction has cost me lots of relationships in the past but the buzz is too strong. I need to know why I behave like this and how I can stop

just stop reading, watching, listening to the stuff which takes you towards sex craving. Plus you need to have someone real sincere who can stop you to do it
