This fetish cursed my life

Hey, I really don't want to nagging about the situation. So I just jump to the main question. From all my life the only thing that could arouse me was strong legs and mean girls. And this fetish. Normal stuff are not arousing for me(intercourse)

My question is, without any specific arousal for penetration, is the physical stimulation enough to stay hard and enjoy ? Or since I lack the erotica mind about sex, I wouldn't be successful ?

Any ideas or suggestions ??
