My Uncle Wants To Fuck Me - Need Advice!?

Hi everyone,

So - I've gotten my self trapped between a rock and a hard place, so to speak. You know that stereotype of the overly sexual and inappropriate uncle everyone claims to have? My uncle on my moms side is the personification of that stereotype. He's 60 years old and the type of person who has always been a little bit too close for comfort after a few beers and keeps telling dirty jokes at the dinner table.

Anyway, I'm a 28 y.o. guy and bisexual, which my uncle knows. Ever since I came out he has been "joking", telling inappropriate jokes about me and what he supposes I like and do and he has smacked by butt when I walk past him. He has done this in the open in front of my parents and his own family (wife and kids) but everyone has kept shrugging it off as him being himself, even though I know that his family thinks it's embarrassing that he keeps acting like this.

Anyway, in the beginning of last year was my moms 60th birthday, and of course my uncle and his family was invited to her party, along with a bunch of other friends and people. Everyone present got pretty hammered, including yours truly. Here's where the trouble began - during the party my uncle did one of his usual remarks about how much I like dick and how he bet I'm good at blowjobs and this time I got kinda turned on. Throwing caution to the wind, I ended up leading my uncle to my bedroom and I sucked his cock at my moms party. He jerked me off a bit as I gave him head and when he came I swallowed his cum. The whole thing was incredibly erousing as it happened, but afterwards I just felt shameful, partly because he's my uncle and partly because he's married with a family.

I have taken a distance from him since, but he doesn't seem to care. When we meet he stills tells jokes as normally, but now he grabs my ass or rubs my cock on the outside of my pants when noone's looking, pressing his dick against my butt and telling me how much he wants to fuck me, make me feel like a girl, how he misses my mouth, etc etc and it has started getting to the point where it's making me really uncomfortable. I can't really tell anyone in my family and ask for help or advice - because duh! - and I don't know how to tackle it.

Any advice? Has anyone else been in this type of situation?
