What's wrong with me?

My son tells me he loves me a million times a day and it irritates me. I should be happy but I feel like he is too much. Also he comes into my space a lot. Like a lot.

I ask him to finish his breakfast, he says I love you and runs to give me a kiss. I am trying to get his sibling into bed, he says I love you. Falls all over us. Am dressing him up and he is struggling to kiss me, even in the bathroom, he will follow me and say the same. I love the love and I gave him lots of hugs and kisses and made sure I tell him I love him, but now it is getting out of hand. He doesn't even give me a chance to tell him I love him first. He says it when it ain't even necessary. To make it worse, my mom has a man who she is dating that she says he is just like my son. She is talking about a problem, all he says is I love U. Like dude listen. I don't know if my son is lacking some kind of attention or if am just over thinking it but damn, it is too much. I should appreciate it. I didn't want to raise a man who never tells the people he loves he loves them and now he does it and I fear my reaction will make him stop. Where is the balance? How do I stop being irritated? How do I teach him to say it in a somewhat appropriate situation without killing his love? Since beginning this post, I have gotten 5 flying kisses, 2 hugs and 4 I love yous and 1 kiss. And it goes on all day like that.
