Killing Lizards

A somewhat strange little collection of short stories in this Penguin 60s edition. I have only read one other William Boyd,and it too was short stories. I just don't think he gels with my interest / appreciation.
The first story was by far the most enjoyable for me - but I have to say the cover is excellent, and probably pushes up a star from the stories. For all the stories there was a strange, and unappealing theme of young men with some sort of sexual issues: The first was about a young boy with mommy issues, the second a child star who has trouble adjusting to adult life, the third a typical public schoolboy story about a boy who lies out his sexual experiences to his masturbating friends, and the final about a young man living in Nice - more masturbation and lack of success with women.
I don't know if this is William Boyd's repertoire, or if he also writes about other things - it may be that I never find out.
