F O R G E T the studies !!! When I think of sex, i dont curl up with a "study"1 I dont know if any of this matter to you but I take 3200units of VIT E EVERY DAY! That combined with my 52 years and a 30 year marriage to a loving CG partner (read hubby) I have too many urges for HIM!! HE is now taking E to keep up... When he's on a biz trip as Barb said there's always that tool with batteries included !!! HAVE FUN !! Joyce
