Chin Augmentation Choices
While there are only two methods of chin augmentation (implant vs. bony repositioning), the correct answer for you can not be exclusively determined in a side view profile. As a male the equally important question is what type of change do you want in the front view. (more or less square) This additional important chin dimension assessment will guide your chin augmentation method. Since you have called your chin 'spiked and small', that would suggest you want a wide and more square chin as well as more horizontal projection. That would lead one to the implant option.
If change of shape is needed, sliding genioplasty is probably the best option. The chin can be made into different shapes
A closer up profile photo of your face as well as pictures from the front would be helpful to give you the best advice. From the picture you provided, it does not appear that your chin is severely recessed, so I would not recommend a chin implant based on that one photo. I might have a different opinion after examining you or seeing other pictures.
