Indeed. Though I often take breaks from having intercourse (in part to avoid pregnancy/STDs, but also because I've found that few women can please me as well as I or another man can), since studying Taoist techniques ~8 years ago I've used it a number of times with others. The most obvious benefit is that premature ejaculation is a non-issue: you can essentially go as long as you want, not having to worry about wearing out before your partner has a chance to be satisfied.
Sex can be measured in hours rather than minutes if you like. Men are often inclined to fall asleep or stop once they ejaculate. Desire fades. In this case sex really does become energizing rather than draining. Just be sure to mix things up a bit rather than doing 4 hours of constant thrusting (one's partner may not enjoy such an experience very much, no matter how much lubrication is used).
With the particular method I studied, PC exercises and breath control were just the basic techniques. For someone open to esoteric exercises energy circulation is also taught (and this is the part where it gets into spiritual cultivation). Rather than just dealing with multiple orgasms, instruction is given on expanding the orgasm to encompass the whole body. One can just scratch the surface of the method and be quite happy with it, while it's possible to go much deeper than I've bothered to so far.
