These two are taboo words in bed, they sound way too rude, they're more suitable for a guys talk when they're boasting about their bed feats, rather than real bed talk. It's like "lick my pussy" vs "lick my cunt", the latter being rude and completely off. Трахать is okay. Sometimes "взять" is also used (возьми меня, я вся твояbut somewhat more common is "выебать"/"ебать".)
Post #3 seriously answers your question, man. No kidding.
