I'm 45 and have never reached a climax. But now I have met a new man and have hopes this is going to be a permanent relationship. So do you think there is any hope I could learn to orgasm at my late age?

That isn't a "late age" at all. Lots of women learn to climax when they are 45-plus. However, you do need a bit of professional help from a female doctor who is experienced in dealing with what is rather grandly called "anorgasmia". Please begin by contacting the Institute of Psychosexual Medicine, the website is www.ipm.org.uk
