Let me be the first to congratulate you!
Nursing school is exciting, scary, fun, hard work, terrifying... you'll love it. Some guys have said that they feel they have a difficult time in SOME aspects of the whole experience, specifically in OB and Peds. My DBF is an LPN and he told me his program was amazing and he always felt welcomed by students and staff alike. I have had two fellow male students. Can't speak much for either of them because they both had problems right from the beginning though... not showing up for clinical got one of them kicked out first week of this semester.
Hope it will be a positive experience for you!
