What's the Name of That Book??? discussion

This was a book I read about 20 years ago about a young man whose best friend went to University. The friend was nicknamed 'Balls' or maybe 'Ballers'. The main character formed a relationship with a girl who slept with Balls / Ballers and I think he may have then killed his girlfriend after perhaps reading her diary? At one point the main character takes a long coach trip - possibly to visit his friend - and wets himself because he cannot hold out any longer.

The main character was possibly autistic but without insight into his condition.

The Talk of the Town by Ardal O'Hanlon maybe?

Yes! Thank you so much - I have been trying to remember this one for months.
