Breathe. You are live human. Male. It is perfectly normal.
Enjoy the hell out of your erections and stop worrying. As your hormones settle in, you’ll find that those pesky ones go away.
I know a many men in their 60s who take little blue pills to get an erection. They have horrible side effects, but they still take them.
Enjoy your erections while you get them naturally, without “blue pills”.
