Had sex after 5 month without PMO. Was good, very good. But i have any doubts!

Hi guys. I?m a single 48 yo.
I had my first meeting after 5 months of reboot. I took Cialis 5 mg for safety. It worked very well.
But I noticed that it took me many minutes to get a good erection, may be 5 to 10 minutes since we started the contact. After that I have no problems.
This is normal? I realized that I got very nervous and maybe that caused this. But I would like to know if it happend because of PMO for so long, and if this slowness to achieve an erection goes away with time.
Thanks guys for read me, i accept opinions!

I think the issue is that you got nervous, it?s hard getting and maintain a erection while nervous and anxious. We tend to worry about our erection, it will subside when you get more relaxed with the girl you?re dating.

Thanks CB for your opinion!
