I think you are on track.
What dose of Cialis did you have?
Cialis (Tadalafil) is one of four PDE5 inhibitor drugs. These work by amplifying the arousal nerve signal that arrives at the penis, and give you a better erection that you would have had without it.
They also improve the blood flow in the flaccid penis, which helps protect the penis during the period of no or few erections. (A penis needs regular erections to maintain health and prevent shrinking.) Cialis is particularly good at this because it's long lasting. The 5mg daily low dose or 20mg twice weekly will give continuous dosing, i.e. continuous protection. (All the other PDE5 inhibitors are too short lasting to be able to do this.) For this reason, you probably should continue taking it unless it's causing you side effects - the benefits are not just for erections. Also, you will have moved on in a couple of months, and a PDE5 inhibitor may work better for erections now.
However, for erections, you might need the event dose drugs, which would be 20mg Tadalafil or 100mg Sildenafil (urologists mostly recommend trying the max dose of PDE5 inhibitors when aiming for erections during penile rehabilitation). If you do this and you're on the 5mg daily Cialis, I would suggest you skip the daily tablet when using the event dose tablet.
Something else you might try to improve erections for penetration is to use a cock ring such as the Durex Pleasure Ring (but not a pump constriction ring - they are for use with a pump only). The more gentle cock rings apply gentle pressure to the outside of the penis which is where the veins draining the erectile parts (corpus cavernosum) are, and very gentle pressure on these can considerably help maintain blood and increase pressure in the corpus cavernosum, giving you a firmer erection. Cock rings are available to go around the base of the penis, or the base of the penis and scrotum - both ways work, and don't need to be particularly tight. When the blood pressure increases in the corpus cavernosum, it actually takes over the role of squeezing the veins shut. (These are not the visible veins on the outside of the penis - they're a couple of layers deeper and not visible.)
