User183737 - I agree that it's very patronising and irritating when male posters feel the need to comment on some topics that they obviously will never understand or need to, but isn't it a good thing if some men want to read and learn more about the female side of things?
The majority of non-solo sexual acts do involve a man and a woman, so is it a bad thing if one participant has a greater understanding of the feelings, emotions, wishes, concerns of the other? Should we have a thread titled 'Why doesn't my DH care about learning what gets me off in bed' closely followed by another thread asking how dare pervy men read threads about female orgasms? [man=perv, naturally, unless it's your male loved one, of course]. Yes, there will be some pervs seeking their jollies, but they'll find a way regardless of what normal, sensible, reasonable people do or don't discuss on a public international forum.
Men clearly have no input in discussions about their own experiences with periods, but do we want to go back to the old days when they would blush and run away at the mere mention of it and it defacto became seen as an embarrassing secret that women must never mention. Now we have TV adverts, news articles and even a politician unabashedly mentioning her own menstruation in Parliament and then going on to raise the issue of period poverty.
Is it better if men think that, when the baby needs feeding, their DW just whips them out, gets it done in five minutes with no difficulty, pain, leakage, supply issues, latching problems, refusal, potential BF-shaming scenarios etc - no real difference from them just going and whipping out their chap when they need a wee - or is it a good thing if a BFing mum's DH actually understands the realities of it for her (and for the baby)?
Do a search on MN for discussions about ED, vasectomies, premature ejaculation, prostate issues etc. and you'll find loads. Should women be banned from talking about these issues that will never directly affect them, but which can and do cause very real concerns for them both as a couple - whether with practical implications for their joint 'relations' or just because people tend to, you know, care about their DP?
And as for the TTC board, surely everybody knows that, when a couple has trouble conceiving, it's never EVER down to any kind of 'fault' on the male's side....
