Not sure that I see a question in your sharing about how you masturbate. If you are asking is it ok than of course it is ok. To each his own as far as I am concerned. For me I mostly masturbate when others are watching occasionally for personal relief. I really get off when I am performing for a group of onlookers especially if they are cheering me on with cat calls, whistles, hooting and the like. Hell I can squirt 3 or 4 feet sometimes when so aroused by all that attention.
