In all honesty, if you just want to get this guy laid then set him up with a call girl. Find a classy agency, ask the madame or master of the agency questions about STI testing to see if they keep their employees safe and such, and make an in-call (ie. at the agency's brothel) appointment.
However, some people are just late bloomers or even just not interested in sex, regardless of their gender or the gender/orientation of a potential partner. But if this guy is bemoaning his virginity and/or has a spank bank of 100 GB of porn on his computer then he just needs to get his rocks off. Professionals are there for no strings attached services, and so long as he's not so freaked out it aught to be a positive experience that will give him the confidence to have better sex in the future with ladies of his choosing.
