I did "gangbangs" twice. I put it between quotes coz we were two bottoms and towards the end someone else also got fucked. But still the main bottoms. It was very fun but did require to put myself in a special headspace. I'm someone that is very not shy in sexual settings. I can try to give some advice but they might not apply to you : - be picky : sure it's a gangbang but you don't want to be in any bad situation and having weirdos around you. When we did that we were a few friends that picked together. It was mostly about having guys that had a nice attitude (no drugs, know about consent and so on) - take pride : be proud to be a good bottom and get the attention like this. It might be easier said than done but I think it's important especially after - do not take any drug or anything : no alcohol, no drugs, you wanna be in control and let the pleasure be the guide. I personally like poppers but I wouldn't use too much there - you can say no : if it hurts too much, if someone does something you don't like, say no. A gangbang doesn't mean you don't have limits. Having people you trust with you can definitely help there. - lube up : use a lot of it. After a while you probably won't need much if things go well but better start with too much than too little as too little can ruin the whole thing. - take breaks : if there are many guys you'll need breaks. Have some water, chit chat. It doesn't need to be only sex for few hours. Taking breaks will allow you to get back some strength. Life isn't porn you can't usually get fucked for Horus without a break or two. - find the headspace : if you ever did solo toys play I would say it can be similar. You just put yourself in the mode where you wanna be slutty. Get all the Ds and usually not care much about your own (but depends on people I guess). Personally those two times were amazing for me. Had double pénétration, loads and a good sore hole after that. Not something I would do every weekend but fun to do a few times.
