Fair play to him but if hes got enough sexual attraction in a woman to get it on , he must be bisexual

I can accept that there are guys out there who are good looking but I dont fancy them or get a stiffy if I meet them but give me a sexy woman and I a climbing up the flagpole

It's like Gareth Thomas, how on earth did his wife not suss out he was gay , unless he was bisexual ?
