Should I play wrestle with my son?

Hi i’m a mother of one and 33.

I’m in a really difficult situation which started a couple of days ago. It arose after play wrestling with my 10 year old son, who’s a big wrestling fan. Having recently moved house and school he spends much of his free time with me and as such likes to play wrestle with me. When we last wrestled he asked me to put him in a bodyscissor hold to see if he could escape. This at the time seemed totally innocent as we play similar games often, so I put him in this hold where you wrap your legs around your opponents tummy and squeeze with your thighs. I did this till he gave up we went on wrestling. Later he asked me to put him in a headscissor (like above but thighs around head) again after some squeezing he gave up and we then finished playing.

Now my dilemma. The next day while checking the history on my computer I find that he has been searching these holds and looking at some sexually inappropriate material relating to those wrestling holds. After seeing what he has looked at online I feel I may have made a big error in judgement in putting him in any kind of scissor hold as I possibly inadvertently indulged him in some kind of fetish!

I have not yet approached the subject with him. But he has subsequently asked me to put him in another scissorhold. I refused under the premise of being to busy to play, but this wont do forever.

Is there any way of stopping him looking at such inappropriate material? One problem I am having is as there is often no nudity on such sites they are not picked up on parental filters and much of the material is on popular video websites.

However my main problem stems from my son wanting me to put him in a wrestling hold that could have sexual connotations. I am very good at applying this hold as I have very strong thighs, and it is one of the few wrestling holds safe enough to apply at home that I can make him give up in. This makes our play wrestling a lot more fun, particularly for him. So with this in mind it would be a shame not to use it if its not going to cause any sexual confusion.

Should I talk to him about it? Should I continue to play wrestle with him in the same way? Is it ok for a mother to apply such a hold to her son?

Any help would be much appreciated
