psn= sex with a blow up doll.
On the plus side you "plug in and go" and when you're done, there's no awkwardness afterwards, you don't even have to cuddle with it. Not to mention your doll is not a whore and as a result you won't have to compete with (many) others to get in there whenever you want.
On the downside...it's a blowup doll...it's not gonna talk to you before, during or afterwards (some people actually like that)
xbla= sex with a prostitute.
On the plus side, you know for a fact that it's another Human there with you and not some machine as they'll talk you and tell you all kinds of shit even allow you to have all sorts of kinky parties and what not.
on the downside, a good prostitute always asks for the money up front and because you know she's good at her job, she has "plenty of customers" who can sometimes take up a "bigger bandwith" than you.
Moral of the story?
Either way, you're getting laid. Choose which "sex" is better for you, enjoy it and move the fuck on, no need to wag your dick around around boasting about where it's been because either way you look like a dumbass.
