The word penetrates Good evening RTG I saw your edit here and have been wondering why you consider using the word in that sentence immature You haven t been reverted on it but penetrates is okay to use when talking about sexual acts It s in a lot of the sources as penetration and there are times when we need to say vaginal penetration anal penetration etc Hello Enters is in most cases we might hope more accurate Penetration is what a marauder does Entering is what a guest does Can you tell me it s the wrong choice without telling me what you are more used to finding Entering is so vastly familiar also that comparing the two in that way is all but irrelevant You feel you need to say vaginal anal penetration sometimes but can you explain one case where nothing else is sufficient Can you reason that the first description we make be of the marauder rather than the guest I say a lot here for one word but every word has a meaning and the more artful word is not always the more suitable while it is almost always more attractive without evaluation Unless you reason that enters be unfamiliar because penetrates is familiar which is an arguement that doesn t make good sense enters is not only the concise choice but also the accurate one Penetration has a further meaning which is to push beyond a barrier Enters just means enters and that is what we are trying to describe where I changed the wording The entrance to a tunnel rather than the breaking of a barrier I didn t say that enter is incorrect or less familiar I m just saying that penetrates is not immature and it is also just as correct accurate as enters That is the reason it is so commonly used in reliable sources about sexual acts Not to mention you can t actually say veginal entrance or anal entrance and not have it sound silly in comparison to saying vaginal penetration or anal penetration For example we have an article called Sexual penetration Not Sexual entrance So as to your question about sometimes needing to say vaginal anal penetration I d say yes How else are we to say it without adding awkward or unneeded words such as Most women say that entrance into the vagina does not cause orgasm Or Most women say that vaginal entrance does not cause orgasm Not only could entrance mean anything in those sentences such as just entering and not moving it doesn t flow right Saying Most women say that vaginal penetration does not cause orgasm is usually understood to mean sexual intercourse penetration by the penis which also signals actually moving Although it would be ideal to say vaginal intercourse in any of those three examples I just don t think that people are goig to analyze penetrates vs enters in the way that you have upon seeing the terms in a sexual article Like I said using penetrates is pretty commonplace
