Is a girl fucking a guy with a strap on gay?

I’m pretty sure my str8 mates would say it is gay having anything put in your butt, but, saying that I’ve spoken with str8 guys about being fingered during oral sex and they like it and understand that guys have some nerve endings back there which feel really good.

What if you told a str8 guy he would be fucked with a strap on but with 2 girls, is that still too gay?

I had a chick fuck buddy years ago and during a drunken sex driven conversation one night she mentioned that she’d love to fuck a guy with a strapon and I told her that I was keen.  She fucked me with it maybe half a dozen times and it was great.  I’m not sure it is a topic that would bring up with a conservative or anti-gay/bi chick I was dating.

A little off topic from our usual speedo talk but I was writing about it over on www.BisexualDave.com and thought I’d ask you guys what you think.
