From your description of your strength of erection you should manage to achieve and maintain another one in the same session. However you may struggle with a second orgasm as a common side effect for many is an apparent desensitisation making 'getting there' very difficult even with vigorous wanking?
Yes. I had a two hour session this afternoon. I got great wood during the first hour. I decided not to spluff. I went down to a semi while I chatted with the girl.
Then after a break, I got back up to a full boner which lasted all through the second hour. In the end, I didn't "get there", but it didn't bother me.
The same thing happened on occasions in the past.
It was loads of fun though. I wouldn't go back to the old way if I had a choice. Having a boner "on demand" really puts you in the driving seat in the session.
Before I followed a fixed formula which worked. It was based around the girl working me to get wood and then teasing things out without losing wood- which worked with good SPs, and with poor SPs, not so much.
In the most recent sessions, I really stopped worrying about it, and was able to relax and be more experimental.
I'm wary of becoming dependent on it, or developing tolerance.
