I have oily skin; is it okay to apply foundation every day?

I have oily skin, so sebum production is excessive, and it gets even worse when the weather is hot like it is these days. I apply foundation every day; are there any other people with oily skin who experience this? The coverage is good and it doesn't dry out my skin, but I'm worried that it might make my skin even oilier. I'm wondering how often I should apply foundation to keep it at a reasonable level, and I would also appreciate recommendations for matte foundations that are good for oily skin.
I am wondering if the foundation clogs my pores, blocking sebum and causing it to fester inside, thereby worsening my acne. It is fine now, but I am worried that if I continue using it, the clogging of my pores might become severe and develop into acne later on. I would like to know if it is safe to continue using it.
