There is no special andrology in medical college, but some disease anatomy is mentioned in some disciplines, but obstetrics and gynecology accounts for a whole book. Therefore, there is no need to be embarrassed. On the contrary, after clinical practice, some people have a strong reaction when they see the need to insert a catheter, but they get used to it (but don't worry, girls are generally not allowed to insert catheters for male patients). Mainly their own mentality. Don't think too much, you'll be fine.
