Girls do not find me attractive because i am in a wheelchair, they think that i cannot get an erection, when in fact, it is only ,my legs that do not work. what should i do and how should i explain to girls that i can use my penis

If those girls think like that then tell them, its out of their own ignorence and stupidity that the undermine some one who is unable to do something which they can. Dont bother trying to explain to bitches cus they only gonna have sympothy for you. Theres alway ssomeone out there who gonna appreciate you for who you are and wont care what you are or arent able to do. If some girl tell ya you cant get an erection just tell her to fuck you cus god may have disable you legs but not your penis for petes sake
