You seem ignorant and naive about late in life virginity.
Make sure you're well groomed and dressed for your initial meet, but nothing too fancy.
Keep the conversation light, casual and informal, and don't worry about archaic conventions such as holding doors open or pulling chairs out for her; just do whatever you feel comfortable doing.
It doesn't make you any better or worse a person or lover.
That's all on you and how you handle yourself otherwise. You may be inexperienced in dating and sex, but you aren't a virgin. Especially when it is with someone that you trust and care very deeply for.
You have Christians who have done EVERYTHING but intercourse and yet think they are still "technically" virgins.
A virgin is simply a person who views themselves as a virgin.
No, you don't need to reveal the fact that you're a virgin to a date, and I would recommend not doing so until and unless the woman seems interested in you sexually, and furthermore, it looks as though sex is about to transpire -- you still aren't obligated to reveal this information, unless the situation at hand warrants your furnishing an explanation for your fumbling around and/or nervousness due to a lack of experience.
No, it isn't overrated, and not even your very first time, despite what some might be wont to say.
Excuse me for wanting some intimacy with my intimate acts.. If you prefer your intimate acts to be with strangers and hookers and whatever else, fill your boots.
