Like the title says I have to tell her sooner or later, any advice is welcome.

Perhaps, just ease or slowly talk about it. Something like this is a delicate procedure that needs to be spoken about. Not many see this way of 'life' as something weird. But really were all weird in this world hehe.

From what you're saying it seems as if she knows about the hose but not necessarily the encasement. I suppose you could approach it slowly and tell her its a "facet" of the fetish. Some of us crossdress, some of us love feet and some of us encase ourselves! I wouldn't advise pressuring her to try it straight away but ask her to be open about her feelings on it. If she feels too uncomfortable to take it too the bedroom, don't beat yourself up over it. Life's too fucking short to worry about the little things!

Well name of the game has been baby steps. So far she is fine wearing socks over her arms when we are in bed so I gave that a while then I talked about encasement and said I had done it, so I'll give that time to sink in and go from there.

Thats the way! Remember that relationships are much more healthy/important than the fetish, though there's nothing wrong with having your cake and eating it!

I told mine very early in the relationship when she asked if I have any fetishes. I showed pictures of women and couples, no solo men. (Nylonmichelle's pictures/clips are a good starting point). I have since backed off of the encasement aspect but have routinely politely asked her to her pantyhose. She's happily obliges it easy for her because she wears them anyway already. Like yours, she likes that she can do something so simple that excites me in public. It builds. I'm not pushing the encasement because I want her to feel completely comfortable with me i.e.- her telling me about her kinks and watching her preferred adult materials (BDSM) with her and alternating with non-encasement nylon fetish DVD's. It's a process.

I have had a former girlfriend who once volunteered to try encasement about a week and a half after telling her about it. It depends on the girl/woman. Play off her reactions to it. Some girls will jump right into it while others will take time to get to that level of comfort. Remember that one of the primary driving forces in female psychology is their comfort level. Part of that is familiarity.

Sort of work it into conversation. Be prepared - bookmark/save pics and/or clips that you want to show her as examples of what you're talking about. Remember that pantyhose is just a common garment for women, similar to socks or boxers/briefs for men. Most won't immediately get that it's a fetish object for you. Your girlfriend already gets this basic aspect about you and has accepted this about you and that is wonderful. She sounds like she has lot of positive qualities.

Don't rush. It's like having sex with a woman. If you're in a rush and try to force it, it's much less fun than when you take your time and relax and let her arousal build. She'll wrap her mind around it in time. You have no control over that time frame, though. However, just like when you make love to her, if you take it easy and let things build after telling her, good things will happen.

Well encasement with the gf was a sccess She is now a fan of it problem solved lol.

next step will be pics to show us :-)

I will do my best on that step and see what I can accomplish
