I noticed that the area on my briefs which the penis touches feels a bid damp. is this normal?

Yes: Most men have some degree of "post-void dribbling" of urine that is the cause of the damp spot in one's underwear. Often related to poor voiding habits and, in men >age 50, to increasing prostate size and/or weakening pelvic floor/sphincter muscles that come with aging. Almost always an annoyance and not a sign of a significant underlying problem. Pelvic floor exercises/good voiding habits helpful
