I have erections that confuse me to this day
Why are you erections confusing?
It is rather bothersome when I have erections in public
I'm sorry that's happening to you.  If they persist, I'd suggest talking to a doctor about it so you can avoid further embarrassment due to these public erections of yours.
I don't think I will be talking to anyone about my erections
I understand that the whole situation is a little embarrassing. Still, if it continues to be a problem you really should talk to a health professional.
