#6 Again

So I actually went through with a booking. Yay. With #6 again - shy IT dude. I've seen him three times now I think and every now and then swap an email. Totally no hassle client. Still trying to work out why he doesn't have a girlfriend and I'm wondering if there is some issue with penetration in sex? For every time I see him it tends to just be kissing, touching, maybe a bit of oral sex and
