As someone who was lucky enough to carry out my adolescent fumblings and get into my twenties before safe sex became a by word, I feel a little sad that services like OWO are disappearing from many girls services, I've also noticed that a lot of girls who used to offer CIM have also begun to drop that aswell.
Having said that ,even in my youth,to deny that STDs weren't around would be foolish and the prime consideration of both clients and escorts must be their well being and health and only do what they feel comfortable about. Obviously both escorts and clients are at higher risk than the majority of people due to the numbers of sexual partners (dont even think about it expedentially !!!!)
So while I may mourn those services, as many have said on these boards before, there's alot more to a 'liason' with these gorgeous women than certain services.
