Hi confused,
I thought I’d offer a woman’s perspective on the issue.
Personally, it doesn’t bother me when my boyfriend looks at porn. I realise it is natural and that it doesn’t mean that he loves me any less. However many women don’t feel this way (especially if they are feeling insecure) and every time you look at these pornographic images of other women, your girlfriend probably feels unattractive and her self esteem takes an even bigger dive. This would affect your relationship and not to mention your sex life.
I would suggest you work on making your girlfriend feel loved and secure and try to cut back on the porn a bit, but be honest with her about it. Explain to your girlfriend that it doesn’t mean you don’t love and adore her.
Goodluck
