Hi I am 15 and was saved a around the age of 11. Since then my walk with Christ has been very strong. I would definitly consider myself a strong christian, but I have been struggling with lust for the past 2 years or so. It is easy for me to control myself from watching porn, but often times I feel it is hard to stop myself from masturbating. At best I will go 10 days without masturbating before I start doing it again. When i start doing it again I can stop for quite some time. This was always an issue, but two months ago I started dating a girl. We met at a church camp and we have a very solid relationship. We both have talked and are saving ourselves until marriage. We trust each other a lot and have shared a lot of dark things about our past, but I can't seem to find the strength to tell her. I know how hurt she would be if she knew. Most of the time I think about her when I masturbate but even then I know it is still wrong. Should I tell my girlfriend that I struggle with lust? I truly love her and I know it is early but she is the type of girl I would love to marry. If I don't tell her sooner or later it could get worse as time goes on. What should I do, and how should I do it?
