From my experience, a number of women with a solid training background (at least 1 - 2 years) and good genetics should be able to get 135 for 2 - 5 clean reps (full ROM to the chest, no bounce) on a bench press. Most certainly 100 x 6 - 8 or something is wrong with your training, and at least 45 - 50 lb DBs for 8 in flat presses, upper arm to at least neutral.
I train a female with a long history of a hereditary degenerative neuromuscular condition that can handle 35 lb DBs for 8 - 10 flat presses. It can be done.
