Real concern: Is my partner still into me?

In a steamy session, a guy struggles with insecurity as his partner barely touches him. Reassured by her words, he continues until she suddenly stops, leaving him questioning their chemistry.

Real talk, real concern. I've been with my partner for a while now and I can't help but wonder, is he still into me? I know we're in a committed relationship, but sometimes I catch him checking out other women. It's not like he's cheating or anything, but it makes me feel a little insecure. I mean, who wouldn't? I know we're supposed to be exclusive, so why is he looking at other girls? Don't get me wrong, I still love him and I know he loves me too. But this little nagging doubt in the back of my mind won't go away. I've tried talking to him about it, but he just brushes it off like it's no big deal. But it is a big deal to me. I want to know that he's still into me, that he still finds me attractive. I know we're in a relationship, but I want to feel desired. I want him to want me.
