I think it would be more ethical to tell people your views of the pros and cons. That said, including your views about the psychological and quality-of-life components of the pros and cons, as well as the medical ones, would not be unreasonable. After all, PrEP is a "lifestyle drug" - people don't take it to cure any disease, so it's only appropriate to compare it to the alternative approaches to managing the risks of sex.
Not everyone has the same psychological reaction to the reality of taking a drug regularly to ameliorate one particular risk of an optional (though highly desirable) activity. Personally, I find that PrEP does not change my perception of the risk of bare sex, but it does lower that risk to a level with which I'm comfortable. This is from the point of view where my sexual relations have been bare almost all the time for nearly 20 years now, and those risks have manifested more than once... though in truth, they also did a time or two before all the sex was bare, which is perhaps among the more educational experiences I've had.
