Most people don't necessarily let it STOP them from either being intimate or in a relationship with someone who is inexperienced, however, they tend to take more time considering it and making sure it's what they want to do because, like I said before, there's a lot of pressure in being someone's first. I don't think it affects communication so much, especially because there are PLENTY of experienced people that suck at communicating, but I do think it has an affect on the dynamic of the relationship. And generally, an inexperienced person might also feel apprehensive about being with someone experienced, it's not a one way thing. It's the way it is. As much as we try to make sex a super casual thing, the truth is that intimacy affects us deeply. And honestly, if someone is super into having sex with virgins, it's usually because they've fetishized it. I would much rather someone be a little nervous about getting with a virgin because that tends to mean they respect the fact that this is their first experience, and they usually have much for considering for the emotional affects of anything they do together.
