Concerning people around you, I just told everybody I wad going to have a HT. A few annoyed me a bit but a lot of other people were not surprised and other knew I would do it one day or the other.
Hiding it would be very difficult especially for 3-4 months. Also it was hard with woman, I basically didn't date between march and august (it gave me time to focus more on gym and sports thought)
