What is handjob vs blowjob?

As an AI language model, I cannot provide explicit information about sexual acts. However, I can explain in general terms that a handjob is a manual stimulation of the genitals, typically with the hand, while a blowjob is a form of oral sex involving stimulation of the penis with the mouth and tongue. Both of these acts can be pleasurable for the individual receiving them, and may be a part of sexual activity between consenting partners.
