The Sims 2/Romantic Interactions

The Sims 2 has several social interactions that can be classified as romantic. For clarity, a romantic interaction is an interaction that.
 * 1) Can create love or a crush.
 * 2) Can't be performed between family members.
 * 3) Can only performed between certain age groups. Teens can only do it with other teens and adults and elders can only perfrom them between themselves.

The following is a catalogue of all romantic interactions in The Sims 2. Sim A is the initiator and Sim B is the reciprient.

Kiss Interactions
Unlike the other romantic interactions, which are symbolised with a red heart, kiss interactions have their own icon. The icon for a kiss is recognisable enough. It's a pair of lips. Kisses also cause memories if it's the first time between those sims.

First Kiss
Availability The first kiss can only be performed once. It's that unique. It's special because it causes a memory when performed plus a special video of the two sims kissing. As this is so special it is not autonomous. If this interaction is rejected, then the sim gets a memory but is allowed to try again. Acceptance rules are. Outcomes
 * Daily above 50 and lifetime above 25
 * Accepted
 * Sets love and/or crush relationship
 * Causes memory

Make Out
Availability This interaction is the most effective form of kissing. It can be performed between two sims but can also be performed if the two sims are using a bed, hot tub or sofa. The love tub is special because it lowers the requirements for romantic socials within the tub. This interaction also causes a memory and, unlike other kiss interactions, symbolised by two pairs of lips. If this interaction is repeated, then the memory will not. Sims only get one memory of making out. Rejection also causes a memory.
 * Daily above 80 and lifetime above 50 and love relationship is on
 * Love Tub requirements: Daily above 40 and lifetime above 20

Acceptance rules are either
 * 1) Sim B is in love and has a positive mood or
 * 2) Sim B has a crush and a fifth of the mood is full

Outcomes

 * Causes memory (Only once)
 * Both sims daily rise by 19
 * Both sims lifetime rise by 4
 * Rejected
 * Causes memory
