Will I regain lost sexual sensitivity in my nipples after 3 months post-op?

My BA was 3 months ago (30 years old, 350cc silicone under muscle). I'm numb in some areas of my breasts, but I have feeling in my nipples. I had a high degree of sexual stimulation in my nipples pre-op and now it is almost non-existent. I can feel touch, but it doesn't stimulate me in the same way. This has caused a decrease in sexual libido. I'm worried I might have lost my sexual desire by cutting off nerves to my most stimulating area. Is it possible for my nerves to still regrow?
