My boyfriend keeps touching my stomach. What does this mean?

The stomach is a sensitive area, he is trying to show you affection. There are other areas he could be touching, but they might seem more sexual, so he is choosing an area that isn't sexual but is still close contact.

It sounds to me like he has feelings for you and wants to show it.

Perhaps he has picked this up from movies etc when a man strokes his pregnant wife's belly? Maybe he even wants to have kids with you?

If you are going out - why don't you just ask him. And if it makes you feel uncomfortable, then certainly tell him! He probably thinks you enjoy it, otherwise he probably wouldn't do it.

One concern here is that he has his hand on your belly because he is "testing the waters" to see if you will react to him going "down south".

Maybe he will start with a gentle tummy rub, slip down to your pubic area, and then go for the home run! If he does this, then your relationship will have become sexual - make sure you are ready for that before you allow it to happen. He must respect you, and you shouldn't let him take advantage.
