Failing a relatively light bench with pins is damn near zero downside and all upside, provided you are authentically trying to push each rep (which is psychologically much easier to do than, for example, on the squat). And keep in mind failing on the bench is usually due to losing control of the bar ("misgrooving"), not necessarily absolute strength deficits: I had many workouts that went like 4,5,5,1 or 5,4,5,1. I didn't repeat those weights and got 3x5 the next few increases.
Your target every time is 3x5, but if you get pinned by the bar, rest a little and get the rep done. Reason being that if you stop doing reps because you miss them in a set, you are reducing stress (as I said, a workout of 5,3,2 is less stressful than a workout of 5,5,5), which is the opposite of what you want. The point is to get weight on the bar, and ensure you are inflicting a heavier weight on your body than last time, even if the sets become shorter. You don't need to consider a programming change until you are consistently only able to get doubles or singles (i.e., 2,2, and 11 singles), mostly because of time.
You also might be at the point where you need to progress with triples (5x3). You're over 40, and describe being a weak bencher, so this isn't all that surprising. If you can consistently get 3s, just get 5 sets of 3 and progress as normal, adding weight to the bar each time. Do *whatever you can* to increase weight on the bar. That is the most important thing, even more than keeping the proscribed rep range. That is what leads to strength increase. 5's are the *means* to produce the strength increase, not the end. If they stop working, use a different means.
You are in fact, NOT certain. Repeating 160 to get you head on straight might be the move, but you have to be unracking 165 pounds in 2 bench workouts from now, regardless of whether you think you can do it.
As has been stated, you also need to gain twenty pounds immediately. Bench is very sensitive to bodyweight.
