You don't want to warp the photo.
That would work.
but it wouldn't represent you.
The best way to still keep it looking like you but masculine is to use makup effects.
You can add more 'dirt' look to your face, add beard stuble look like a five oclock shadow, add in more eyebrow hair, lower the hairline on the sideburns, etc.
if you have any sort of adams apple, you can highlight that area using a cutout tool or wand and add more contrast and shadow to amplify it.
Same with your jaw and neck, if you don't want to add hair. you can just add more shading and shadow to make it look more masculine.
Warping the face: I only reccomend if the people who are going to see the pic are never going to see you in person.
They will be able to tell. even if subtle, it will seem off.
