i was in the same boat regarding bench two months ago. I changed my routine to this
Incline dumbell press( alternate sides so hold both in the air and lower one at a time) 4 sets
Pushups 4 sets
Decline bench 4 sets
Dips 4 sets
Then id finish off with the pec deck 15 reps low weight for 7 sets, it may sound crazy but it gets a shitload of blood pumping to your chest at the end of your workout
I went from benching 50 dumbells for incline and 55 for flat and now im doing 65 for incline and 70 for flat.
Btw im also only resting 1 min max in between sets
