putting my foot in it

there are things apprently that you should not do on a first date.

1) talk about the ex
2) talk about your best friend (who happens to be of the opposite sex)
3) talk about sex

1)
talking about their ex is gonna bring back feelings for someone else, even if they are ones of hate... which does not allow feelings or focus to be directed at you. all of which either kills the mood or makes you look like a lump of cheese.
talking about your ex makes them think your either a) a psychopath b) a stalker c) still hung up or d) all of the above

2)
talking about your best friend of opposite sex (even if its a mutual friend) is not wise either.
especially mentioning that you share their bed occasionally... cos your date aint gonna believe you that there isnt any hanky panky going on. and even if this friend is like your bro/sis to you... they aint gonna believe it. they are on a date with you cos they think your attractive, imagining you (their attractive date) in bed with another and nothing happening.... they won't believe you!

3)
ok this one people might disagree with me.
but you don't know their sex life or lack their of. their history etc.
and your either gonna sound really horny/desperate or really prying or just totally put your foot in it... so no, its not sexy to talk about sex.

BUT OF COURSE
I only know these things, cos i've done all these things. and now i feel like a complete idiot.

sharing the shame :)
