So I am looking basically for a pack and play packer, but I want something that can basically help me get off during sex. I've been looking for basically a packer or strap on that can also stimulate me during sex(with a girl). Hopefully you can understand what im trying to say. Is there anything like it or at least close to it out there? If anyone has such a thing, what's your opinion on it? Is it any good? Is it worth the buy?

Also, what packer would be best to buy? Of course I want it to feel realistic and I want to be able to use it for sex. Any suggestions?

Yes. There is something. Ihave never used it, but its a mango produce tat basically has a little nub on the back of the dick. If you do a search for mango products i think you will find it

sadly the mango product is unobtainable, i tried earlier in the year and never got a reply form them the best thing i have found that works to "get me off" while my girlfriend and i are intimate is the doc johnson ur3  6 inch, i just cut the suction cup off to form a slight cone shape and i use a rodeoH harness. positioned right it works everytime. how ever if you are really sensitive and have a vivid imagination like me it can end up causing your "fun time" to end prematurely the first couple times, if you catch my drift 

i have a dick that has a suction cup on the back and i just use it to jerk off as i have no one to have sex with  but it works wonderfully the suction cup and the back edge rub against my dick and i get off here is a link to one in the same colection as the one i have but i got mine form amazon for like $25 or something similar.
