Many have a similar attitude to do. You have to wonder how many unknown sti with no symtoms are being spread by some of these girls. but then, when you consider how paranoid clean some of them are. A bit of a give away is when they insist you have a shower first and they join you and clean you up, then immediately after you have cip they are up and washing themselves out. Its a wonder they can actually produce any natural lubrication, but in most cases its all artificial anyway. You don't have to worry about imprenagation in reality except for the innocent (yeah, any left ?) or those collecting.
Did you realise that most condoms now DO NOT have any form of spermicide ? Found to cause breakdown of the condom and fairly useless. So if the girl wants to get pregnant for any reason bbfs might be their first choice and collecting used condoms could be their second.
