I was on the swim team when I had my port put in, so it was important to me to put it somewhere that wouldn't be seen in a swimsuit. That one was below my left breast, but I had trouble when I lay on my stomach with it rubbing my ribs and with my bras irritating it, perhaps it was placed too high. This second one (had it for 7 years) is placed on my right side, even with my nipple, just forward enough to be in quite a bit of breast tissue. I am small busted. I used to be a good B, but am now an A. I have no problems with it. With certain types of needles I can still sleep on my right side even when it's accessed!. It doesn't get bothered by my arm. I am self-concious when it is accessed about it showing when my husband and I are intimate, so I usually wear a tank or sport bra and tuck up the tubing. He has told me that it doesn't bother him. It's me that it bothers, but just psychologically, not physically. It's also a great place (didn't think of it when it was placed cause I wan't even dating hubby) because it's out of the way for taking care of daughter. When she was nursing - oh wait, she still is, hahaha - but, I mean lots, it was nice cause even when it was accessed, it was out of the way for her and neither of us were ever bothered by it.
