72.
I was in my 50s at the time, a 'holiday romance' is Spain. Despite her age I was, and have no reason to disbelieve her, only her second partner, her having been married from teenage to being widowed about 3-4 years prior to meeting her.
Despite the lack of partners in her life, she appears to have been pretty open-minded to anything her husband had suggested, so we went through the whole cycle of missionary, to doggy, to oral, to anal.
The one thing she wouldn't do was take my cock all the way into her mouth due to her gag reflex
but the blow-jobs were fine, and she did swallow.
