If you have little experience when it comes to intact males it is only natural i suppose to feel a little apprehensive. But really, whether he is intact or not, his penis should not be an issue - it should be him you want to date, not his penis. Speaking as an intact male myself (from the UK), and having travelled throughout the USA - mainly for business but for pleasure also - i have had the pleasure of engaging in, shall we say, erotic encounters, with a number of ladies. Some of whom found themselves in the position you find yourself in now, ie suddenly coming face to face with an intact penis for the first time and wondering what to make of it. A couple of them were very curious about it, some were less so but still seemed a little apprehensive and one seemed downright disgusted by it (that relationship didn't last very long as you can imagine!) but as soon as we got down to business they instantly wondered what all the fuss about intact penises was all about.
There is nothing weird about an intact penis - in fact since the overwhelming majority of males around the world ar intact it is the circumcised ones which may be considered weird! but if it's not something you are used to then it is only natural to be curious.
Just remember a few things - his penis, be it intact or otherwise, means alot to him so be sure to show it some respect, after all, you wouldn't want him to poke fun at or show disgust at your breasts for example. Secondly, be sure that you learn how to give him the pleasure he deserves and how his penis responds to your touch - believe me, he will respond in kind and then some! And thirdly, have fun! and enjoy exploring the joy of experiencing intimacy with a natural, intact, 100% as God intended, penis and all the pleasure it and the man it is attached to will give you in return!
