This is indeed true and I can verify it because I've been in three very sexual relationships.
Here are a few key points that porn ruined for me:
I would get turned off by the following:
- boobs not being my favorite size 36D (see
here for what that looks like. I would get angry at my girlfriends because they didn't look like those bouncy, firm breast implants. I looked at their breasts and I thought to myself "What, I don't want these milky jumping things, I want firm, strong boobs I can put my dick in between!"
- hairy pussy (shave yourselves! Again, used to porn)
- not sucking deeper than the tip (yeah, sorry for having a big dick and expecting them to suck like the porn pros, but only one of the girls sucked me deep to the maximum because she was in love with me. Wait a minute.. they all did that after a while because I got them really horny)
- not wanting to do anal unless serious discussion or not at all
- not wanting to do blowjob without a condom (this girl was really lame and inexperienced)
- not allowing me to make her feel hot by caressing her hips. No, she wanted slower foreplay (granted, she had a boyfriend she was cheating on with me)
- thinking my ejaculation was 'gross' (granted, this one was a virgin)
The girls that succeeded in pleasing me the most were - despite their non-ideal porn looks - very hot (and one was very experienced in bed, so she made the foreplay heart-poundingly hot as did I) and we were a good match.
