Having sex because of an injury

Precious

Hi guys, hope you're all doing good, I need your help urgently please, a Friend of mine on Facebook (tho I've not met her) said she needs my help concerning her brother, she said he brother had an injury some months while ago playing football, which affected his spinal cord and now he can't play again till he improves, so she said that the doctor said that he should be having sex regularly to improve. Please guys I want to know how true it. For my second question, I was suggesting we use condoms but she said that he brother doesn't cum if he uses condom and that he goes for test every Monday. please guys, is it advisable for me to do it,and yes the girl and her elder sister lives at Texas while the guy and their mom lives in my country (Nigeria) and we stay not far from each other. As for next year, he will be going back to Texas for checkup and my reward for sexing him will be that, I will get to live with them in Texas and they will carther all my bills and Education. Please guys how true is this and should I agree.
