Family overseas for 3 weeks. I only get a few punts in a year due to family and work commitments. Now it is the perfect time!

After abstaining for a week, I went to have a punt early this week but I couldn't get it up. Tried 3 more times, burned through a bit of cash but it seems my libido is down and I couldn't finish. I don't think its physiological, I'm just not as sensitive anymore and the urge is not there. First time I'm contemplating of quitting punting. I'm over 45.

Anyone else had similar experiences, did Viagra help?
