You’ll probably get so many different opinions.
My wife and I have been married for 14 years now with three kids. Not once did I ever think we both be okay with self pleasure until just this year.
She obviously doesn’t crave intimacy like I do (is it a guy thing?! Yeah probably) so we are both 100% onboard with keeping our bedroom life to us and if she needs to release so goes for it. If I need to I go for it and when we are both on board we then are able to do it together.
I think it has eased a lot of pent up tension for me because I’m a guy and I enjoy it and it takes less for me to release than it does for her and so instead of nagging her about it all the time, we are both okay just doing it for ourselves whenever we feel the need to.
I don’t feel any less worthy and it has strengthened our marriage big time! So, as long as you and your significant other are both okay with it, go for it!
She probably uses a variety of things 1-2x a week while I am more frequent and it helps me sleep better when she’s working graveyards sometimes!
Hope that hells!
