You can blame repressive upbringings and for the hating penetration part, possibly a combination of repressive upbringings and society's expectations of what women "are supposed to like". I mean, I LOVE penetration (the deeper the better)! It's the main reason I'm straight and not bi! And I have both clit stimulating toys and penetrating toys. Strangely enough, I had some repression in my own upbringing as well, but it manifests itself differently. I have no qualms about penetration or handling a penis (I LOVE giving hand jobs too!!!), but I do have problems with French kissing, and to a lesser extent, with blowjobs (I'm trying to at least get over the problems with blowjobs, and really, it depends on who I'm with on that).
I have to say I had problems with penis because of myths...
but when I started selling dildos & became the porn watching queen...
I shed a lot of doubts & misconceptions...
it was liberating & exhilarating...
I have a hard time now with my male partners being open about sex & their fetishes because it has been deemed dirty by women...
FUCK THAT!!!
I almost married a cross dresser (not bi or gay... just a little fucked up... XD)
I still have fantasies about slowly taking a legging off with my teeth...
lightly wrapping it around his neck & fucking his brains out...
but again... maybe I just got bored with the over exposure...
the experience was good though... made me more open & tolerant... =)
PS it takes talent to give good hand jobs...
its harder then most people think... =O
blow jobs are hard for most women...
it doesn't help if the guy has a crap diet too...
then the precum/cum can be not very yummy... fruits & veggies do help...
if your partner is forceful during blow jobs... help them understand you would like to go at your own pace...
explore it like its a new & wonderful animal... XD
french kissing... I have had some amazing kissers & some really shitty ones...
and the shitty ones are the worse... you just want to get away... XD
try coming up for breath more... licking the lips... nuzzling the face...
its a polite way to break up bad kissing...
and sometimes you can retrain them through taking the lead...
holding the back of the neck to stop them from pressing too hard...
make it seem like you're just playing & teasing with being dominant...
eventually they take your lead... =)
