Welcome CJD87,
You have come to the right place for your question. Search engines, key in breast forms for men or silicone breast forms. Silicone are the best starting around US $150 and range upwards of $1,00 or more. The silicone is covered by a velvety soft polyurethane skin. Being a plastic surface can't replicate the feel of skin but, the silicone is pliable like a female breast. Online sites have tables to figure the size right for your measurements. There are spray on or tape adhesives to go braless (depends on size) or secure to chest for wearing a bra. The weight of the forms when adhered to your chest jiggle when you move. Hope this helps.
Enjoy
Jamie
