Be it your partner or someone your on a date with.
Most Helpful Guy
You can take it personally and dump him for lack of respect, go shopping for another but if you're fishing for ways to train him... forgetaboutit he's wrong for you and will revert back to old ways, even if he learns how to avoid being caught at this. In fact, most beauties tell me they can tell if guys are gay or not if they DON'T check them out on the sly. They watch, they know. Thus, they/we all do it somewhat.
So you write this Q b/c you want to keep him but your sensitive feeling are hurt that you are not his only perfect princess at the ball. The only thing you can change is YOU, so if this is your path, make a game out of checking out others, gals & guys and have fun commenting on others. They used to call this people watching and its loads of fun especially at side walk cafes.0
